Sen. Hillary Rodham Clinton's trio of victories over Sen. Barack Obama last week appears to have convinced a sizable number of uncommitted Democratic superdelegates to wait until the end of the primaries and caucuses before picking a candidate, according to a survey by The Washington Post.

Many of the 80 uncommitted superdelegates who were contacted over the past several days said they are reluctant to override the clear will of voters

At the Democratic National Convention in Denver in August, there will be 796 superdelegates

"You're going to see a lot of delegates remaining uncommitted," said Rep. Mike Doyle (Pa.), who has not endorsed either candidate. "There's a sense that this is going to Denver not resolved."

So far Clinton, with 242 superdelegates, has had more success soliciting their support than Obama, who has the backing of 210.

"If superdelegates were just intended to automatically vote for the preference someone else expressed, there wouldn't be any purpose,"
