“There is a Soros based movement (Daily Kos related) that are out to disrupt our primary, to ensure that Santorum gets the nomination.”
Even if Santorum does not get the nomination, this startegy is keeping Newt from getting the nomination. And Newt is the one they are desperate to stop.
Santorum is so divisive, that they see him as the easiest to beat. And believe me, after Santorum lets his arrogant manner take over once he thinks he can't be beat, he will open his canyon sized mouth and stick both feet into it.
Which is exactly how the Democrats see him and why he will be so easy for them to beat.
