Sens. Barack Obama and Hillary Rodham Clinton competed for Democratic convention delegates across three states on Saturday, locked in a landmark struggle for the party's presidential nomination.

A total of 158 delegates was at stake in the Louisiana primary and caucuses in Nebraska and Washington. Caucuses in the Virgin Islands offered three more.

Clinton began the day with a slender delegate lead in The Associated Press count. She had 1,045 delegates to 960 for Obama. A total of 2,025 is required to win the nomination at the party convention in Denver.

Republican contests in Louisiana, Kansas and Guam provided John McCain a chance to advance closer to the 1,191 delegates he needs to make his nomination official.

The Arizona senator began the day with 707 delegates. Former Arkansas Gov. Mike Huckabee, with 195, and Texas Rep. Ron Paul, with 14, were his only remaining rivals following Mitt Romney's withdrawal from the race.

The day's contests opened a new phase in the Democratic race between Clinton, attempting to become the first woman in the White House, and Obama, hoping to become the first black.
