They are very keen, in knowing that Santorum will be all too easy to beat. There is a Daily KOS group that has been formed that go from open primary to open primary, with orders to vote for Santorum, to get him nominated.
This is an actual plan. Because they have so much they can destroy Santorum with, that they are holding all of it until he gets the nomination.
Santorum as our nominee, will be an utter disaster, especially after the Left hits the polls in record numbers and also votes in more Democrats for both houses.
Yeah, I know the left is salivating at the opportunity to run against a candidate who wouldn't be able to shut about why he thinks contraception is "not okay" and why we need a war on internet porn. It would be a dream come true for the Democrats who are so desperate to avoid talking about the economy that they have already taken great pains to manufacture this phony "war on women" talking point. If the Democrats could sit down in a lab and create their most ideal opponent, Rick Santorum would pretty much be it.
