Four weeks after claiming the Pennsylvania Senate nomination, Rep. Joe Sestak continues to have an awkward relationship with many leaders of the state’s Democratic establishment — with the two-term congressman so far neglecting to check many of the boxes that ordinarily would be routine for a candidate trying to unify his party after a hard-fought primary.

It’s been nearly a month since the May 18 primary, and key local party leaders have not been in close contact with Sestak. His unorthodox campaign organization is unnerving Democratic officials, and his public comments suggest he hasn’t forgotten the rough treatment he received from the White House and the state party establishment, both of which worked furiously to deliver the nomination to party-switching Sen. Arlen Specter. All of it has Democrats wondering about the pace and direction of his bid against Republican nominee Pat Toomey.

Perhaps this is sour grapes coming from party insiders who picked the other guy. But if the insiders are correct — that Sestak lacks staffing and an actual campaign manager — that’s a problem. And we hear that Sestak isn’t the ideal boss. (“On Capitol Hill, Sestak’s office is known for its high staff turnover rate, and several staffers left his primary campaign over the course of its nine months in existence. He has relied heavily on his brother and his sister, who manages his prolific campaign fundraising, for his House races and also for his Senate bid.”)

A bigger problem is that Toomey is beginning to set the terms of the campaign — making hay out of the job-offer scandal and painting Sestak as out of the mainstream on everything from energy to Israel. There’s still time for Sestak to get his act together, but he better do so fast before Democrats decide to spend time and money on more viable survivors of the Republican wave heading their way.
