I honestly don't think Murtha's paying any attention to his House race. He's too busy basking in the media attention. But that will likely change after the second quarter fundraising reports come out!
I would guess Murtha would still have a significant lead against Irey head to head, but I'd also bet his approval ratings have taken a hit. And they're going to continue to drop as Ms. Irey 1) becomes better known, and 2) keeps calling him out on his abhorrent behavior, comments and votes.
This is going to be a race. Remember, John Kerry only managed 51% of this district's vote. And Murtha can't realistically hope for such a Dem turnout this time around. Plus PA has already shown an anti-incumbent mood from earlier in the year.
This is the best time for Irey. I guess the fundraising reports will get enough of Murtha's attention to get him to start campaigning.
