Six weeks ago, no one would have predicted that Mitt Romney and Rick Santorum (in photo) would virtually tie in the Iowa caucuses. Romney was barely campaigning in Iowa, focusing mostly on New Hampshire. And Santorum was rarely even mentioned in campaign coverage (this is the same guy, after all, who lost his Senate re-election race in 2006 by a whopping 18 percent). Though Romney wasn't able to increase the percentage of support he received in the 2008 caucuses, he has a strong organization and the discipline for a national campaign. Santorum's appeal is nearly exclusively with conservative Christians, which could be hard to carry forward. As the Wall Street Journal editorial noted, "Santorum can sometimes sound like a charter member of the cast-the-first-stone coalition, when most voters prefer a more tolerant traditionalism."
