Obama narrows superdelegate gap

While Hillary Clinton snagged the biggest-name backer of the day, Barack Obama has reportedly added two more superdelegates to his fold.

Richard Machaceck, a Democratic National Committee member from Iowa, has declared for Obama after the Illinois senator won 16 of the 29 national convention delegates at stake in congressional district conventions over the weekend, the Des Moines Register is reporting.

And the Associated Press says US Representative Ben Chandler of Kentucky, grandson of a former two-time governor of the Bluegrass state, is supporting Obama as well.

Clinton is hoping that the endorsement of North Carolina Governor Mike Easley might lead to a couple other superdelegates down the line.

Obama continues to eat away at Clinton's lead among the elected officials and party leaders who are likely to determine the Democratic nominee. Less than 300 of the nearly 800 superdelegates have yet to declare their preference. Obama already leads in total delegates and total popular vote.
