Two polls released today show two quite different results in Pennsylvania's 2010 Senate Republican primary. A Franklin & Marshall poll, which we wrote about earlier, showed Sen. Arlen Specter leading ex-congressman Pat Toomey by 15 points, with 42% undecided.

A Quinnipiac poll released this morning, however, finds the tables turned -- Toomey leads Specter by 14 points, 41%-27% with 28% undecided (March 19-23, 423 GOP RV).

Specter holds a huge lead in name ID, according to Quinnipiac, with a 45%/31% favorability rating. However, just 29% of Republicans have a favorable opinion of Specter, compared to 60% of Democrats and 41% of independents.

The more-conservative Toomey received a 14%/6% favorability rating, with 78% unaware of who he is.
