The Franklin and Marshall poll of Pennsylvanians out this morning shows Republican Pat Toomey leading the incumbent, Sen. Arlen Specter, for the first time in three months, 33 percent to 29 percent. Toomey leads Joe Sestak, 27 percent to 19 percent. “Independents favor Toomey over Specter (32 percent to 17 percent) and over Sestak (35 percent to 5 percent).”

The poll also tells us that Pennsylvanians aren’t paying the least bit of attention to their governor’s race, it seems. Among Republicans, 66 percent don’t have a preference in their primary (state attorney general Tom Corbett leads with 28 percent), and 71 percent of Democrats don’t know who they support; Dan Onorato leads with 11 percent.

I’m not quite sure why F&M has so many more undecided voters across the board compared to other pollsters:

The data included in this release represent the responses of 1119 adult residents of Pennsylvania, including 964 registered adults (483 Democrats, 353 Republicans, 102 registered as Independent/Other, and 26 who refused to identify party). Telephone numbers for the survey were generated using random digit dialing, and respondents were randomly selected from within each household. Survey results were weighted (age, education, race, region, and gender) using an iterative weighting algorithm. The sample error for this survey is +/- 2.9 percentage points.
