Is It Over Yet?

CBS: Rick Santorum is poised to suspend his bid for the presidency on Tuesday, removing the last significant obstacle in Mitt Romney's now all-but-certain march to the Republican presidential nomination.

Santorum will make the announcement at a press conference in Gettysburg, Pennsylvania shortly, a senior member of his campaign staff told CBS News.

My first thought: He didn't want to get embarrassed in his home state in two weeks. My second thought: He may be crazy, but at least he's smarter than Newt Gingrich. And my final thought: Santorum making his announcement at Gettysburg seems so apropos.
