CHATTANOOGA (WRCB) – Early voting is officially underway in Tennessee for the state primary.

The gubernatorial race is on the ballot, and the Third Congressional District seat that will be left vacant by Zach Wamp.

In Hamilton County, from now until July 31st, you can vote at the Brainerd Rec Center, Northgate Mall, or the Hamilton County Election Commission.

Congressman Wamp made his way to the election commission after a short kick off rally Friday afternoon.

It was a busy morning for the election commission Friday.

Wamp greeted supporters as he cast his ballot.

The latest NBC Nashville News poll numbers show Wamp trailing Knoxville Mayor Bill Haslam by double digits in the governor's race.

Wamp says he plans to focus his campaign on the undecided which was about 36 percent of people surveyed.

Wamp thanked his supporters, but not before taking shots at his opposition.

"Tennesseans have a big question. Are they going to engage and elect their own governor or are they going to let the money and interest determine how the nominee is who will most likely be the winner in November," say Congressman Wamp.

So far more than 400 voters have come to the election commission, not including the satellite locations.

In 2008, 26 percent of registered voters participated in early voting. The polls will remain open until 6:00 p.m., Monday through Saturday.

Knoxville Mayor Bill Haslam took his message to West Tennessee Friday, with a rally in Memphis.

Lieutenant Governor Ron Ramsey started the day in Memphis, then headed back to Middle Tennessee.

And Democrat candidate Mike McWherter spent the day in Jackson voting with his family.
