The Clinton campaign wasted no time with this one:

Obama gave Clinton an opening, and she’s going for the jugular. Seems like a smart move - but is it enough?

I first saw that ad on Daily Kos, and this is part of the commentary that accompanied it:

Seem to me kind of a lame ad. For it to be effective, the Clinton team will have to convince voters that Obama really doesn’t understand them, that he’s too, you know, “different” to understand them.

And boy, are they trying! Even John McCain is jumping into the ring, remarking on Monday that Obama’s “bitter” comments were “elitist” and a “contradiction from what I believe America is all about.”

So we’ve heard from Clinton and McCain - what do Pennsylvanians think about their so-called bitterness?

Apparently, some of them don’t think it’s such a big deal - or maybe they’re just sick of hearing about it. Clinton got an unexpected reaction from Pennsylvanians when she brought up the “bitter” comments in Pittsburgh yesterday:

At a forum on manufacturing attended by members of the steelworkers union here, Clinton’s comment that “many of you like me were disappointed by recent remarks he made,” was met by loud shouts of “No!” When she suggested Pennsylvanians might find Obama’s remarks “offensive,” again there were loud cries of “No!”

Obama had spoken earlier to this audience, and the loud applause he received suggested some of the people who didn’t like Clinton’s tone supported the Illinois senator. But Obama had not been jeered earlier in the day when he slammed Clinton, and the New York senator was applauded loudly for much of her speech, as she laid out her agenda to protect manufacturing jobs.

We’ve said before that Clinton has gone all in with her anti-bitter campaign in Pennsylvania, but I think she better have a few more tricks up her sleeve if she wants to win the state. With a week left until the primary, it’s not a good sign that people are already sick of hearing about bitterness - I know I am, and judging from the crowd’s reaction yesterday, Pennsylvanians are too.

Start shuffling the deck, Clinton - you’re gonna need more than this to claim victory on April 22.
