And I was particularly pleased to see this recent poll that shows Casey leading Santorum by 7 percentage points.
The good news? Casey is running +4 among white voters and +14 among seniors. (The latter margin is critical in Pennsylvania -- Florida is the only state east of the Mississippi River with a larger share of 65-and-over residents.)
The bad news? Santorum is polling well in the northeast region of the state, Casey's backyard. And Santorum is polling very well (for a Republican, anyway) among blacks. He receives nearly one out of four African-American votes.
Unless these voters are all rabidly anti-gay, Casey can make inroads with them. Even if they're pro-life voters, Casey should have a shot at winning their votes -- he is economically liberal, but pro-life (like his father, the ex-governor).
