I just watched a little bit of Fox News when stopping by to see my dad, and even Fox is admitting, albeit begrudgingly, that Rand saw an increase in support due to his debate performance, and that Scott Walker and Christ Christie have lost the most ground lately. The fact that CNN's own stinking poll put Rand ahead of Christie and Kasich is proof positive that they were trying to undercut Paul's performance and largely failed, though they definitely didn't help matters with their dishonesty.
CNN accomplished 2 of the things that they set out to do, which was to make Fiorina and Rubio rise in the polls. They may have partially succeeded in undercutting Paul's performance, but clearly not to the point they wanted to given how his grassroots support is beginning to coalesce following his rock-solid answers on foreign policy and the drug war, resulting in that recent straw poll victory in Michigan. I'd venture a guess that Rubio's guy assaulting Paul's strategist probably has something to do with Rubio's numbers in some of these states not actually being as strong as the national polls are suggesting, ergo frustration leading to a cheap shot sucker punch.
