Superdelegates Ask: Which Candidate Has the Coattails?

Ten of Pennsylvania's superdelegates have yet to back a Democratic presidential candidate ahead of the April 22 primary. And while Clinton is expected to win the balloting, Bloomberg writes, some—especially several freshman congressmen up for reelection—are concerned that her "high negatives" might inspire more Republicans to come out to vote against her, hurting their own chances.

"If we nominate Senator Clinton, it is possible we are going to stir up the passions of people on the far right who otherwise would not be very excited about this election," one told Bloomberg. The issue of which candidate might provide coattails for superdelegates could be crucial for Clinton, who will net only a handful of committed delegates from the primary itself.
