Polls are open in four states voting in crucial primaries in the Democratic race for the White House.
Hillary Rodham Clinton needs a win in Texas or Ohio to salvage her presidential bid. The two states are the biggest prizes of the day. Voters in Vermont and Rhode Island are also heading to the polls.
The former first lady has dropped 11 straight contests to Barack Obama, who's hoping to knock Clinton out of the race with a sweep today.
One voter in Columbus, Ohio, says he voted for Obama because he likes how he can bring "the two parties together." A Cincinnati woman has selected Clinton because she feels the New York senator has the experience to deal with the struggling U.S. economy.
On the Republican side, John McCain can garner enough delegates Tuesday to officially clinch the GOP presidential bid.
