Just did a quick average of this Rasumssen poll and the ARG poll posted a little further down
Romney: 28.5
Gingrich: 23
Paul: 18
Santorum: 11.5
It sounds like Santorum is definitely in decline. I suspected this would happen after his disappointing post-Iowa performances.
Now if only we could get the Paulies to see the light...
It's time give up on the idea of Santorum being a viable candidate and for sane conservatives to rally around Newt, who is the only one that can beat Romney in SC.
