(AP) - After 11 straight primary and caucus victories, Barack Obama is hoping today brings a few more. Hillary Clinton is hoping to stay in the race.
There are 370 Democratic delegates at stake in today's contests in Texas, Ohio, Rhode Island and Vermont. The Associated Press gives Obama the lead in the delegate count: 1,386-1,276. The former first lady has an advantage among superdelegates, 241-199.
Some of Clinton's supporters, including former President Bill Clinton, say she needs to outpoll Obama in both Texas and Ohio to sustain her candidacy.
Meanwhile, John McCain could end the day with all the delegates he needs to seal the deal on the Republican nomination. The Arizona senator already has 1,014 delegates out of the 1,191 needed.
McCain's major remaining rival, former Arkansas governor Mike Huckabee, has a total of only 257 delegates.
