As part of Discovery Channel's "TestTube" shows hosted on YouTube, a guy named Jason Tongen travels around the world learning about the people and places behind the scenes in various cities for a show called "What I Learned". Nice work if you can get it, right?

One of the new episodes centers around Arizona, and while they spent time in Phoenix from reasons I don't understand, but hey, they made it down here and hung out with Ed Keeylocko, Slobby Robby, Isaiah Toothtaker and (of course) God. Solid trip all in all.

What's that they say about every vote counting? Republican state Rep. Ethan Orr now leads Democratic challenger Randy Friese by a scant eight votes: Orr is 27,774; Friese is 27,766.

Meanwhile, in the TUSD race, Michael Hicks is now leading Jen Darland by 991 votes.

With Pima County tabulating another 8,400 or so ballots in the CD2 race today, Democratic Congressman Ron Barber closed some of the gap that Republican Martha McSally opened up earlier today when Cochise County results came in. McSally now leads the race by 1,293 votes.

Pima County Recorder F. Ann Rodriguez delivered another 23,500 early ballots to the elections department for counting and she will begin verifying about 10,000 provisional and conditionally provisional ballots tomorrow. An unknown number of them are in CD2.

It appears that Cochise County has finished counting another batch of votes—and when it was all over, McSally has moved into a lead of 2,078 votes.

We're not sure yet how many votes remain to be counted in Cochise County, but Barber is up by about 4,000 votes in Pima County and McSally is up by about 6,000 votes in Cochise County.

An estimated 47,000 votes remain to be counted in Pima County but it's yet unclear how many of those are in CD2.

More to come as new numbers roll in.

While we have some solid numbers here in Pima County and a few other places, there's no firm number of how many ballots remain to be counted around the state, according to the chart above that recently arrived in a bulletin from Secretary of State Ken Bennett's office.

But there are estimates. The Arizona Republic is reporting that more than 150,000 ballots still need to be counted. And we know Pima County has somewhere around 47,000, although some of those might be invalid.

Among the races that remain tight:

• CONGRESSIONAL DISTRICT 2, where Republican incumbent Martha McSally is holding a lead of less than three dozen votes over Democratic incumbent Ron Barber. We've heard all kinds of numbers about how many Cochise County ballots are out there, but McSally was clobbering Barber there with the votes that have been counted: 8,318 to 3,911. If there are still 25,000 votes to count there, as the Arizona Republic reports, Barber is gonna be losing a lot of ground. For the sake of comparison, there were about 48,000 votes cast in Cochise County in 2012; McSally got 28,242 while Barber got 19,815. So with what's been counted so far this year, McSally is doing better than she did in 2012, but the trend could move in Barber's direction if his team did a better job harvesting early ballots. We're supposed to know more by the end of the day.

Team Barber spokeswoman Ashley Nash-Hahn said this wasn't Barber's "first rodeo."

"Two years ago, we woke up the day after the election with a significant vote deficit, but when the last early ballots were counted, Ron triumphed," she said. "Vote counts will go up and down as the remaining early and provisional ballots are counted, but in the end, when the votes are counted, we’re fully confident that we will continue to win the early ballots, and Ron Barber will win another term in Congress."

Team McSally spoke via Facebook:

Right now, there are still many ballots to be counted and the race is too close to be called. It's critical that every last vote is counted and that all Arizonans have their voices heard.

LD9: Republican incumbent Ethan Orr holds a 67-vote lead over Democratic challenger Randy Friese.

TUSD: Michael Hicks holds a 964-vote lead over Jen Darland.

SUPERINTENDENT OF PUBLIC INSTRUCTION: The Democrats were pretty much wiped out on the statewide level last night, but in the Superintendent of Public Instruction race, Democrat David Garcia only trails Republican Diane Douglas by roughly 26,000 votes. He has a narrow shot at a comeback.

PROP 122: Prop 122, which would allow voters or state lawmakers to prohibit spending money on any program they found violated the principles of the U.S. Constitution, was passing in a close race. The Yes votes were about 28,000 ballots ahead of the No votes. Here's a fun fact: Prop 122 is losing in Pima, Maricopa and Coconino counties, but winning in nearly all of the rural counties.

The biggest Election Day surprise may be Republican John Christopher Ackerley's lead over Democratic state Rep. Demion Clinco in the Legislative District 2 race.

Ackerley leads Clinco by 2,160 votes in a district that is 40 percent Democratic, 25 percent Republican and 35 percent independent. But it's also a district that includes Nogales, Green Valley, Sahuarita and Latino precincts on Tucson's south side. While there are votes left to count, it would appear that the Green Valley and Sahuarita voters turned out, while the Democrats did not.

Pima County Democrats had hoped to pick up a House seat by knocking off Republican Ethan Orr in Legislative District 9. Orr has a 65-vote lead over Democrat Randy Friese. If these results hold up as Pima County sorts its way through the nearly 47,000 remaining ballots, instead of gaining a seat, the Dems may have actually lost one.

In the nine-way Tucson Unified School District race, it appears that voters are picking the same-old, same-old.

Current TUSD board members Adelita Grijalva and Michael Hicks are winning the race for two seats.

Hicks remains 964 votes ahead of Jen Darland, who is in third place in the race. Darland had been endorsed by the Weekly, the morning daily and the Metro Tucson Chamber.

While nearly 47,000 ballots remain to be counted in Pima County, it's unknown how many of those are in TUSD.

• Ann Kirkpatrick

In what was a somewhat surprising turn of events, Democrat Ann Kirkpatrick is going to hold her seat in the U.S. House of Representatives, a fact her opponent, Republican Andy Tobin, recognized this morning with a concession:

I would like to congratulate Congresswoman Kirkpatrick on her hard fought victory last night. The strength of our democracy is shown in our ability to have a peaceful exchange of ideas on the campaign trail and to come together after the ballots are counted.

I want to thank my wife, Jennifer, and my five children who have supported me in my campaign for congress for the past 18 months. They have been my bedrock and I am truly blessed to have such an amazing family.

Last night, voters in Arizona and across the United States exercised their right to vote—a right so many are denied throughout the rest of the world. We have these rights because of the brave men and women in our armed forces who stand duty twenty four hours a day, seven days a week to protect our ability to choose our own leaders.

I am truly grateful for the eight years I spent as a state representative—with four of those serving as Speaker of the House. I had the opportunity to serve with outstanding legislators, both Republicans and Democrats, to see our great state through some of its most challenging days.

My parents instilled in me a heart for public service and it’s a passion I have carried through my life—service to humanity truly is the best work of life.

Pima County election officials still need to count nearly 46,859 ballots, according to county spokesman Mark B. Evans.

Whether all those ballots will actually be counted depends on whether they are all legit, but the vast majority will count.

Here's a breakdown, as of this morning:

The Elections Department now has 14,200 ballots that have been verified as good ballots but still need to be counted.

The Pima County Recorder's Office has 22,528 early ballot that were dropped off at polling places yesterday and need to be properly verified by checking the signature on the envelope of the ballot. There are also 9,856 provisional ballots (or ballots that are questionably in some way, such as a ballot that was cast at a polling place even though a voter got an early ballot in the mail and lost it) and 275 conditional provisional ballots (which means there's some question as to whether the ballot is legit).

It's unknown how many of the ballots are in Congressional District 2, where Republican Martha McSally was leading Democratic Congressman Ron Barber by fewer than three dozen votes, or Legislative District 9, where Republican state Rep. Ethan Orr was leading Democratic challenger Randy Friese by 65 votes.

More details as we get them.

As Pima County continued counting votes last night, Republican Martha McSally closed the gap against Democratic Congressman Ron Barber and now leads the race by a razor-thin margin of 36 votes—McSally's 78,785 to Barber's 78,749.

There are a lot of votes out there to count. Pima County has a big pile of ballots that were dropped off at the polling places yesterday and Cochise County's voting equipment malfunctioned, so all of Cochise County's early ballots are being transported to Graham County for tabulation, according to a statement on the Cochise County website. (That's not exactly reassuring news for anyone who wants an accurate count of the votes.)

In 2012, McSally had a larger lead of about 1,300 votes on the morning after the election, but Barber eventually came back to win, although it took more than a week to count all the votes and the lead moved back and forth. We expect things to play out the same way, although the outcome could be different this time. Stay tuned and we'll bring you updates as we can.
