The former first lady lost two more superdelegates during the day, both in New Jersey, when one switched to Obama and the other moved to uncommitted.

Additionally, Reps. Lloyd Doggett of Texas and Ron Kind of Wisconsin, both superdelegates, endorsed Obama.

"My constituents overwhelmingly chose Barack Obama to be their nominee, and I am proud to pledge my superdelegate vote to him as well," Kind said in a statement.

Further underscoring Clinton's political peril, Rep. David Scott of Georgia announced he would vote for Obama rather than the former first lady, and Rep. John Lewis said he might switch, as well.

Superdelegates aside, results in earlier states show how difficult Clinton will find it to overtake Obama's lead when the primaries resume in two weeks.

In general, delegates are allocated on the basis of popular votes within congressional districts, and any candidate who gains 15 percent of the vote is entitled to at least one.

Clinton won New Jersey with 54 percent of the vote and Massachusetts with 56 percent on Feb. 5. But because Obama ran relatively well, particularly in some congressional districts, she won the delegate competition by only 28 delegates combined in the two states.

Contrast that to Obama's home state of Illinois, he won slightly less than 65 percent of the vote -- and won 55 more delegates than Clinton.

The contests left on the calendar include primaries in Ohio, Texas, Vermont, Rhode Island, Mississippi, Pennsylvania, Indiana, North Carolina, West Virginia, Kentucky, Oregon, Montana and South Dakota as well as caucuses in Wyoming, Guam and Puerto Rico. There are 44 delegates unallocated from primaries and caucuses held earlier.
