There are plenty of Mitt supporters here at F.R. They have been very careful to this point, to keep from getting banned but now they are starting to come out of the wood work, very cautiously at this point but should Romney become the nominee, they will get bolder and bolder, with the "anybody but Obama" defense.
The lesser of two evils is still evil. (Not original but still very true)
I think the reason they're playing their hand right now is that deep down, they know their candidate's a worthless lemon and they're panicking.
So what to do? Pull out the playbook from 2008! Page one: "As much as you hate conservatives, you need them in the end. Send your team to the forum sites and plant seeds of doubt about abandoning the party. Frighten them; tell them they HAVE TO vote for your candidate, or they'll be voting for the other guy."
In a way, this reminds me of what gets done to Mormons who try to leave the cult. Maybe that's the inspiration for these tactics.
Hopefully, enough conservatives will stand fast and not fall for this BS.
