A presidential race that's really close and deeply divisive is entering the final 100-day stretch before Election Day in November.

The matchup between President Barack Obama and Republican challenger Mitt Romney probably will come down to the fall debates, final unemployment numbers and fierce efforts to mobilize voters.

It could come down to about eight states that will decide who wins the White House.

The most contested are Colorado, Florida, Iowa, Ohio, Nevada, New Hampshire, North Carolina and Virginia. Pennsylvania is also in the mix.

The two candidates will intensify their time before voters in the weeks ahead, knowing much of the public will not truly start paying attention until after Labor Day.

The key: Which candidate will people trust more to fix the economy?
