Pennsylvania Politics -- Santorum Sinks Even Lower

AP reports:

Pennsylvania Treasurer Bob Casey Jr.'s lead over Sen. Rick Santorum (news, bio, voting record) has grown even larger in their U.S. Senate race, according to a poll released Thursday.

The Quinnipiac University poll of 1,530 Pennsylvania voters showed Casey leading the two-term Republican incumbent by 18 points, 52 percent to 34 percent, in the 2006 race. That compares to a 50-to-39 percent lead in a July poll by Quinnipiac.

Santorum, the No. 3 Senate Republican, spent part of the summer promoting his new book, "It Takes a Family," on television talk shows. The book compares abortion to slavery and accuses feminists of undermining motherhood.

Casey, a Democrat and the son of a popular late governor, has maintained a low profile and done a limited number of media interviews.

The telephone survey, conducted from Sept. 27 to Monday, had a sampling error margin of plus or minus 2.5 percentage points.

What is really remarkable here is that Casey isn't actually running. He's practically become a hermit, making few appearances and giving almost no interviews. Meanwhile Santorum is cutting his own throat. There seems to be a misconception on both the far left and the far right that their positions are really popular. They aren't. Casey, the invisible candidate, simply is benefiting from the delusions of the Santorum camp.
