On the eve of the 2012 presidential election, polls can't tell us who'll be president come January 20, Inauguration Day.
Major polls, including the CNN/ORC International poll, show the race between President Barack Obama and Republican challenger Mitt Romney all even.
While the polls may show a slight lead for one candidate or the other, most fall within the margin of error, meaning this race is a toss-up. And that's how it's been for awhile, with neither candidate breaking away from his challenger.
The election will likely come down to key battleground states, and that's where the candidates, their running mates, their wives and their chief surrogates were making appearances Monday: in Ohio, Iowa, Florida, Virginia, Colorado, Wisconsin, Nevada, North Carolina, Pennsylvania and New Hampshire.
