Elections 2012

With 13 days left until the Nov. 6 election, President Obama and his Republican challenger, Mitt Romney, both included trips to Iowa and Nevada on their schedules. Each tried to fire up his supporters and cast doubts about the other to gain an advantage in a race that appears essentially tied.

At rallies in Davenport, Iowa, and Denver, both swing states where the election is fluid, Obama trotted out attack lines he's used in recent days against the former Massachusetts governor.

In a number of swing states, early voting means many people are already casting their ballots. Typically, that entails voting by mail or visiting a county elections office.

But in Iowa, satellite voting — where "pop-up" polling stations allow people to vote at convenient times and nontraditional locations — is growing in popularity.
