(NBC NEWS) - All eyes are on Denver, Colorado ahead of Wednesday night's first presidential debate.
It could be the best chance for Mitt Romney to get back on top in battleground states like Colorado, Florida, Iowa and Ohio.
Voters in Ohio camped out Monday night to be the first to cast early ballots in that battleground state.
Most states start voting before November 6th, putting more focus on the first debate.
The latest NBC News-Wall Street Journal poll finds 38%, more than a third of voters, say the debates will be quite important or extremely important in helping determine who they vote for.
