Santorum scares the hell out of me and I would have thought that he like Palin would have been marginalized some time ago. The fact that he's still kicking around after Super Tuesday makes me nervous.
If Gingrich's personal life as I've heard it is accurate, he's loathsome, and that makes me nervous.
Paul's a pipe dream that, although he has some amazing features that have captured a lot of imaginations, comes bundled with bits and pieces of crazy that make me very nervous.
Of the front-runners with a real chance, Romney is one of the most balanced but he still has more than enough govern-by-the-bible in him to make me nervous.
I'm projecting that unless there's an extreme screw-up on someone's part or momentum-changing force majeure event, none of 'em has a chance against Obama. So, by default the also-far-from-perfect Obama is the best choice for President over the next four years...?
