Romney does not appear to be falling for the second political death (or is it third?) of Newt, because his SuperPAC still is going negative against Newt.

Perhaps his team knows, based on internal polling, that for all of Santorum’s caucus wins and next best thing hoopla, Newt remains the greatest threat in big ticket primary states.

This has just started running in Ohio, via Buzzfeed, h/t @RSMcCain who notes, “Further evidence that Team Romney is starting to freak out.”

Rush always says, they will tell us who they fear.
