KNOXVILLE (WATE) - Years of campaigning and more than a billion dollars in political advertising all come down to Tuesday, which is Election Day in America.
The presidential campaigns are putting everything they have left into getting voters into the voting booths.
Democrats and Republicans in Knox County have been making a final push to help "get out the vote," trying to sway any undecided voters that may remain.
Monday marked their very last chance to reach them and get them to the polls to cast their vote.
Phone lines were buzzing Monday at the Knox County Democratic Headquarters, with more than 2,000 people on the list to call.
"Really busy and a lot going on, and just making sure we can do everything to get out the vote. Make sure people get out and there and cast that vote," said Gloria Johnson, chairperson of the Knox County Democratic Party and candidate for District 13 Tennessee House of Representative seat.
It is down to just hours until history is made, as American voters choose their leaders. It all comes down to how many step into the voting booth.
"For the most part, you're just calling people, asking them to get to the polls," Johnson said.
Volunteers are hitting the streets, going door-to-door to remind people that Election Day is tomorrow.
They are also clearing up any confusion concerning polling locations.
"There's a couple of locations that have changed, so we're going to put that personal note on their door to make sure they're aware," Johnson said.
It's much the same bustling atmosphere at the Knox County Republican Headquarters, with thousands of phone calls going out to area residents.
"It's just reminding them that tomorrow is Election Day, and that it's critical that they get out and vote and have their voice heard. Every vote counts and is valuable," said Jacob Swisher of the Knox County Republican Party.
Every single person they reach on Monday's final campaign day is a potential vote.
"We've got people coming in to get their materials to go to the polls tomorrow," Swisher said. "People are looking to take part of the day off of work so they can get their friends and family out to vote."
They hope teamwork will help bring out voters in their party's favor.
"It takes a lot of hands to make the team successful. We have a lot of wonderful candidates this year and we want to make sure we get each one of them across the finish line," Swisher said.
Another task is making calls to other states, reminding voters there to head out and vote for either President Barack Obama or Gov. Mitt Romney.
Republicans were calling in Virginia and Ohio, while Democrats called voters in North Carolina.
