This argument really doesn’t make much sense. Two conservatives are splitting the vote, and Mitt is profiting by that.
And since Newt hasn’t been doing very well, Mitt has concentrated his attacks on Santorum. You can see it on Drudge’s website, where there are constant photos and headlines extolling Mitt and damning Rick. They were bashing Newt earlier, but at the moment they’re pretty much ignoring him.
I’m not saying that Newt has to drop out. That’s his choice. But it is damaging the conservative position at the moment.
The essential thing is to keep Romney from getting a winning number of delegates on the first vote at the convention. But that is harder to do with the two conservatives splitting the vote.
Drudge is a little biased in favor of the gay marriage proponent, you know the one that denied he did it.
