It's possible that Rick Santorum gave up his presidential campaign because of the health crisis of his baby daughter. Whatever. I really can't believe in prayer, Rick, but I understand how a father feels when his little girl is in dire peril. I pray with you, Rick — despite the uselessness of my heathen prayers, and despite the fact that I think you're a total asshole — I hope your little girl will survive and thrive. It's not her fault that you're her father.
It's also possible that Rick Santorum left the Republican presidential campaign because the Party came down on him hard. Maybe he was offered a cabinet position — Secretary of Morality, perhaps — but I don't think so. I think he just ran out of money.
Romney still has to tack towards the center. Who the fuck cares? Obama has tacked so far to the so-called "center" that those of us on the "old" (New Deal) left have no real candidate. All we can do is pick the least offensive of the various piles of shit.
