With Giuliani and Edwards out of their races, we're about to get down to basics. This is now the opportunity for the remaining folk, with endorsements and increased attention, to begin to act like grown-ups--in other words, presidential. Romney, McCain, Obama and Clinton now need to start leading their causes rather than assassinating their opposition. If they can't show some kind of quality of public spirit and attention to issues, they don't deserve even one vote.
I'm still a little puzzled by Romney's lack of performance. I think his lack of fire and perceived aloofness are the causes, along with the splintering of mainstream conservatism, but I'm not ruling out a creeping, smarmy anti-Mormonism. Religious prejudice has not expired. It's a shame.
