It’s not a “dirty trick” for Rick Santorum to encourage Democrats to vote for him in Michigan, as Mitt Romney is now whining. It’s an open primary. If Michigan wants only Republicans to vote in its primary, it can have a closed primary.
I expect there are Reagan Democrats who would vote for Santorum in the general. Let them speak up now and try to get their preferred guy the nomination.
Mitt just sounds like a spoiled rich guy used to getting his own way. He wasn’t complaining back in New Hampshire.
