Rick Santorum is the latest...

...Republican to test the presidential waters in Iowa. This is the same guy who lost his bid for reelection to the U. S. Senate from Pennsylvania by eighteen points to Robert Casey in 2006. Setting aside all of his many faults for just a moment, I have two questions. How deluded must Santorum be to think that he could possibly get elected president? And how desperate must the Republicans be to consider someone who got crushed that badly in his last contest?
