Casey: Sestak would be "very competitive" vs. Specter in primary

From the WhoRunsGov Plum Line blog -- reporting on a recent public radio interview:

Here’s what Casey said:
“If Congressman Sestak runs, the next option is to have a primary that’s not … divisive and acrimonious so that we have a split in the party going in to the general election. That’s my hope.
But he’s a very strong candidate and if he runs it’ll be a very, very competitive primary.”

That’s the first acknowledgment from one of Specter’s Dem establishment supporters of the challenge Sestak poses, and could give a boost to Sestak by helping with fundraising and persuading insiders that his candidacy is real.
