Stephen Moore wonders in NRO

Rick Santorum is obligated to publicly back the incumbent Specter. Santorum believes, probably rightly, that he would not be senator today without Specter’s help. In a city where loyalty is notoriously a scarce commodity, Santorum can be commended for not his public pledges of support.

But Santorum is actively working to undermine Pat Toomey’s candidacy. He has discouraged donors from contributing to Toomey. He has cut TV ads for Specter that portray the senior liberal senator as a friend of the taxpayer. He has staff people in Pennsylvania actively campaigning against Toomey.

Worst of all, Rick Santorum is running around Pennsylvania and Washington, D.C., perpetuating the myth that Pat Toomey is “too conservative to win in Pennsylvania.” This is precisely what liberals said about Rick Santorum when he ran for the Senate back in 1994. Santorum proved that wrong. So did Ronald Reagan, when he won Pennsylvania with a fairly right-wing message in 1980 and 1984. Pennsylvania is the signature state of the Reagan Democrat voter. These are middle class, often unionized, blue-collar voters who are pro-life, pro-gun, and anti-tax.
