Hotline OnCall's Alex Roarty reports that, in Pennsylvania's Senate race, Rep. Joe Sestak (D) and former Rep. Pat Toomey (R) are trying to tie each other to figures seen by some as extreme:

PHILADELPHIA - Whom do you support: Sarah Palin and Christine O'Donnell, or Barack Obama and Nancy Pelosi?

That was the choice Pennsylvania Senate candidates Pat Toomey (R) and Joe Sestak (D) left voters with Wednesday night at the National Constitution Center during their first debate of the general election, a contest marked by both men's unrelenting efforts to characterize his opponent as out-of-touch extremists.

For Toomey, this strategy meant tying Sestak to his support of every major Democratic initiative of the last two years, including financial and auto bailouts, the economic stimulus and the health care reform -- measures Toomey said have crippled the country's economy. ...

Sestak countered by linking Toomey to Palin and O'Donnell, the Delaware Republican Senate nominee who has particular resonance in the Keystone State because Delaware is within the Philadelphia media market. He cited both by name while criticizing Toomey for his stance against abortion-rights, an issue that could hurt the former Republican congressman in the state's moderate, vote-rich southeast region.
