Shira Toeplitz at CQ Politics has her pre-mortem on the Sestak-Specter race today:

“I expected it to be very close, very tight,” {Montgomery County Democratic Committee Chairman Marcel] Groen added. “At the end, Sen. Specter will end up prevailing by somewhere around 6 points. Nobody ever expected him to win by 22 points.”

But at least one local Democratic operative said Specter simply did not play his cards right by going on the air too late against Sestak. Pennsylvania Democratic consultant Mark Nevins said Specter “essentially negated” his own cash lead in the primary — more than $3 million at the end of March — by hitting statewide airwaves just one week before Sestak.

“I thought the window for Joe Sestak had almost closed, and it seems like he got a foot in there and kept it wedged open, and now it’s wide open and he climbed right through it,” Nevins said.
