Feb 06 Caucus Time

Tuesday is caucus night in Minnesota and I'll be going to mine, which takes place at Mounds View High School.
What I don't know, even yet, is who will get my support. It's a difficult decision among four flawed candidates:

• Mitt Romney is not consistent and while he's less apologetic to be a Republican than, say, Jon Huntsman was, his only real conviction seems to be that Mitt Romney ought to run things.
• Newt Gingrich is a loose cannon. He's a great guy for generating ideas, but the job description is leading the executive branch of the federal government, not running a public policy seminar.
• Ron Paul is correct about monetary issues, but his foreign policy isn't realistic. You can regret, as I do, the extent to which the United States has become an overextended imperial power, but you can't just walk away from the empire.
• Rick Santorum seems the sort who has no issue with big government, so long as it can be directed to his interests.

So I'm still not sure what to do. If you are going to the caucus tomorrow, which candidate gets your support? And why?
