Blumenthal reads them:
The polling suggests that each of the top three candidates is positioned to claim at least one victory on Tuesday. But if current trends continue, Romney is poised to win the most closely watched race, in Ohio, and he stands a chance of an upset in Tennessee and is best positioned for the most important prize of all: the lion's share of convention delegates.
Silver downgrades Santorum:
[I]f [Santorum's] negative momentum manifests itself at the ballot booth Tuesday, he could … finish with fewer delegates than Mr. Gingrich on the evening, even though Mr. Gingrich is not expected to be competitive outside of the South.
