(WBIR) Tennessee voters will head to the polls on Thursday to weigh in on a number of key elections, ranging from county offices to US Congress.

One primary race is already gaining national attention after an upset tea party victory earlier this year.

Seven candidates are facing off in the Republican primary for one of the state's two US Senate seats. Sen. Lamar Alexander currently holds that position and is going up against State Rep. Joe Carr, Christian Agnew, George Shea Flinn, John D. King, Brenda S. Lenard, and Erin Kent Magee.

On the day before the election, Alexander and Carr both turned their focus toward East Tennessee.

Gov. Haslam got heavily involved in campaigning for Alexander. The duo made their way across the area with several campaign stops.

"Lamar and I both being East Tennesseans you obviously want to end up in your home and so that's what we're doing. But traditionally this has always been a part of the state that had heavy turnout in the republican primary. We obviously want to see that continue," Haslam said during a pre-election day campaign stop.

During his East Tennessee tour, Alexander worked to remind voters of his stance on the issues.

"I want to be one of those Senators that takes conservative principles and turns them into action," Alexander said.

Meanwhile, tea party challenger State Rep. Joe Carr also spent his entire day before the election in East Tennessee. He's riding the wave of enthusiasm from an upset tea party victory in Virginia that ousted former House Majority Leader Rep. Eric Cantor.

"We went from I hope you can Joe, to I believe you can Joe; and then of course we've had Laura Ingram and Sarah Palin and Mark Levin a number of points along the way where enthusiasm has been injected," Carr said.

When it comes to spending, Sen. Alexander has spent much more than the rest of his competition, raising five times the amount of cash as Carr.

The latest disclosure reports show Alexander spent $5 million compared to Carr's $1 million. Meanwhile, George Shea Flinn has spent the third most at around $500,000.

However, the monetary gap isn't concerning Carr. He said he's won in the past on little money, and hopes to do it again.

"Just to give you some contrast in 2008 in the primary I spent $12,000 as a State Rep. trying to run for an open seat. My opponent spent $150,000 and I won," Carr said.

While Carr and Alexander focused on East Tennessee for the day before the election, on Thursday both said they plan to campaign in Middle Tennessee.
