Caucusing for Romney . . . voting for Obama?

Tuesday (tomorrow) night is caucus night in Minnesota, and it's the first time I'll be convening one.
I had been volunteering for the Rudy Guiliani campaign for much of last year, but with Rudy's implosion after Florida, I'm now back with Mitt Romney.
If Romney drops out after a poor finish on Super Tuesday, however, it does look like I may end up voting for Barack Obama over John McCain in the general election for a couple of reasons:

1)The Republicans in Congress may be more likely to resist a lefty Obama administration than a McCain one, and:

2)Whatever we may suffer from an Obama administration, we can blame on the Democrats. If we roll over and let John McCain strengthen McCain-Feingold, sign off on Global Warming legislation, and clamp down on the blogosphere, we'll have only ourselves to blame.

That said, I will work like hell for the re-election of Norm Coleman and our various state-wide candidates.
