I agree that nobody can attack Romney from the same place Paul can, and I agree that the attack needs to come soon. It also needs to be preemptive, so counterattacks from Romney are coming from a much weaker position.
However, I think the mistake you make is completely discounting a [perceived] Gingrich resurgence: South Carolina and especially Florida (
check out this awful poll) are states where we are extremely vulnerable, and Gingrich (and the others) are practically committing suicide there. They're posturing as "real conservatives" and treating the state like their final stand, and Gingrich at least is likely to do MUCH better than he did in Iowa and New Hampshire, relative to us. If he places above Paul in South Carolina, it doesn't really matter if he's broke; the media will be able to pretend to have a "real" non-Paul contender for second place, and ordinary people will fall back into, "Maybe he's a fringe candidate after all" routine. We HAVE to control the narrative, and I still see completely marginalizing and eliminating Gingrich as a top priority. If we don't, I think we'll quickly lose momentum.
Look at how much the current strategy is making Bill Kristol freak out:

He's pleading to keep the other candidates in the race as long as possible, and I don't think it's just an act, either. He knows that actual support for Romney is weak, and he knows that we're gaining control of the narrative with the calls for other candidates to drop out and support Ron as a conservative alternative to Mitt Romney. The message is SO bold that even the media can't help themselves from relaying it to viewers, and I think it's reshaping the way ordinary Americans are viewing this race. Attacking Romney will obviously further this message...but if Newt Gingrich comes out ahead of us, we just screwed ourselves.
For these reasons, I have to continue siding with the campaign's strategy. I do think they'll attack Romney soon; they seem to be gearing up for it...but I suspect they're trying to get rid of Gingrich first, like I'm suggesting. They may choose to attack Romney earlier than expected if Gingrich looks like he will falter in SC, and that would be a win all around if things go to plan. In the end though, our armchair campaign management means very little: The campaign has their mind set on this strategy one way or another. We (the grassroots) can act separately, but RevPAC is putting out positive ads so far, and we don't have another well-funded vehicle for TV ads.
Note that I do not have blind faith in the campaign on the basis of an argument from authority: They played things HORRIBLY in 2008, after all. However, I do believe the current strategy is working.
