This Wednesday, President Obama and Governor Mitt Romney will face-off in their first debate. Some voters are proudly showing who they already picked as their candidate.
'It's a combination for me of President Obama being so great in his policies in my opinion, and also that he's much better than the alternative,' said Hannah Wheelwright, Co-President of BYU Democrats.
Experts are saying if either Obama or Romney make a mistake explaining policy, it could end up costing them the coveted spot in the White House.
'If either one of them make that kind of mistake it actually could change some people's minds,' said Richard Davis, a political science professor.
While some people registering to vote already know who they will vote for, one poll showed that 20% of people could still change their mind.
In an ABC NEWS/ Washington Post poll, one-fifth of voters supporting either Romney or Obama described themselves as persuadable, meaning they don't support their candidate 100%.
'Independent is how i'm going into this election,” said Jill Reisner, an undecided voter. “I just kind of go into anything open minded and trying to see both sides.'
Persuadable voters like Reisner could be very influential in swing states like Ohio and Florida. “It´s those people who haven´t made up their mind who have the ability to tip the outcome one way or another,' said Davis.
The ABC poll also showed that the group most easily persuaded at this year's election are voters under the age of 50.
