Well, someone needs to tell Rick that we're engaged in a completely different kind of war right now, and that it would really help the war effort if he sent his troops over to help one of the generals who stands a fighting chance of taking out Benedict Romney.
That's what this is all about, in a nutshell. We're going to need some heroic sons-a-bitches, even if they are lowly politicians. Any one of these candidates who goes out in the process of taking Romney out to better the chances of another conservative candidate, will be American heroes.
I think i'll wait until after SC and FL. Or until Rush quits writing articles saying not to rule out Perry yet, whichever comes first. ;)
It was one caucus. An open one, at that. Any one of the 3 of them would be foolish to bow out based on one open caucus (whose results have already changed) or polls that are run by liberal organizations.
If Perry makes a poor showing in SC he'll have no problem bowing out and backing one of the other two. Patience!
