Does Rush own Santorum surge?

(AMERICAN THINKER) — A strong case could be made that Rick Santorum owes much of the credit for his recent surge to Rush Limbaugh — whether Rush wants that credit or not. Events of this past week seem to indicate that Senator Santorum would concur. In the past few days his campaign has wisely exploited some of Rush’s words and they are proudly featuring them everywhere.

The implication — if not the explicit language — is that Rush prefers Santorum to either Newt or Mitt.
