Ryan seems to understand this, which might explain why he's not just running for VP, but also seeking re-election to Congress. Assuming he's a cinch to regain the congressional seat, it would take a lot of brass -- as Bill Clinton would say -- for Ryan to accept the risk of losing his current cushy government job in the event the vice-President thing doesn't work out.
Thus, the challenge some might toss at a guy who seems compelled to self-righteously riff about the unwillingness of others to make tough decisions, might involve stepping aside to give another Republican a shot at the congressional seat and betting the farm that by January you'll be vice-President.
As for Mitt, if Ryan belongs on a skateboard then the overall behavior of "America's next President" during the campaign implies that he probably belongs on an analyst's couch. After all, there's something mighty schizoid about Romney's reflexive flip-flopping. And his increasingly bizarre post-Tampa behavior most recently, his leaked revelations to a bunch of rich donors about his feelings toward 47 percent of America, seems evidence of a politician experiencing a nervous breakdown. Now I'm no shrink of course but evidently there's some deep inner psyche stuff going on in MITT-ROM's cerebral cortex that I'm sure none of us would feel comfortable with.
Neither does Mitt -- I suppose.
Anyway, right now he's got a presidency to win, which at this point, seems unlikely except by way of either divine intervention or some incredible stroke of luck.
So it is, after having spent millions over nearly eight years running for President, this is what it boils down to for Mitt Romney -- faith, or luck.
I can almost hear Clint right now:
"Do you feel lucky, punk?"
