Personally of all the likely candidates, he's the one I want for 2012. If Obama is the Dem nominee (as in, if he does decide to run again) I will vote Romney. The only person who could perhaps give me pause in voting for Romney is if Hillary ran as the Dem nominee, but I'd have to judge her political stance against Romney's at election time.
I personally think Romney would make a great President if elected, much better than Obama.
So you are a Republican after all? Good that you've come out of that closet.
