How is not supporting Paul being desperate? That's being sane and every single Republican candidate wouldn't vote for him including Romney.
Huntsman, Bachmann, Roemer, and I can't believe I'm saying this but possibly even Perry would. Johnson already is. Romney would likely support him. He really does not have a reason not to do so. If Paul loses (after being the nominee) Romney stands to gain some trust from what would otherwise be a very hostile fi-con/constitutionalist/libertarian leaning portion of the GOP in 2016. Romney is no dummy. He played this card in 2008. It's a smart move.
Gingrich and Santorum are the ones that stand to lose the most creditability, if Paul wins the nomination.
