The conservative movement has laid into Obama hard on the Wright controversy, and the organized left (e.g., blogs, pundits, party leaders, activists) have not fought back in a collective sense. Obama and his partisans have fought back, of course, but those in the Hillary camp have not done so and the party leadership (probably in an effort not to appear biased one way or the other) has been relatively quiet as well. The effect is a pretty significant mismatch - it would be surprising if Obama did not lose ground under those circumstances.
[Assuming] she has enjoyed a string of 16 victories in a row over [the next] three months. So at the end of regulation, Hillary's the nominee, right? Actually, this much-too-generous scenario (which doesn't even account for Texas's weird "pri-caucus" system, which favors Obama in delegate selection) still leaves the pledged-delegate score at 1,634 for Obama to 1,576 for Clinton. That's a 56-delegate lead. Let's say the Democratic National Committee schedules do-overs in Florida and (heavily African-American) Michigan. Hillary wins big yet again. But the chances of her netting 56 delegates out of those two states would require two more huge margins. (Unfortunately the Slate calculator isn't helping me here.) So no matter how you cut it, Obama will almost certainly end the primaries with a pledged-delegate lead, courtesy of all those landslides in February.
I believe that Hillary Clinton's campaign left the high road for good with the 3am ad. When she co-opted Barack's message of change, I thought, well, at least now she's on record. If she became president and didn't initiate reform, she would have to answer for promising reform on the campaign trail.
The 3am ad, however, completely ended the charade.
How can Senator Clinton say she stands for real and substantial change while parroting Bush and McCain's politics of fear?
How can she claim superior electablility with an ad like this? She can't appeal to the worst in us better than John McCain can. She can't claim that McCain is playing the fear card when she blatantly played that card already herself.
Senator Clinton's campaign painted her into a corner with this move. She promised us change and instead she brings us fear tactics. Shame on her.
