Rasmussen has the Pennsylvania Senate race a toss-up this morning:

The latest Rasmussen Reports telephone survey of Likely Pennsylvania Voters shows Toomey earning 45% support, while Sestak picks up 39% of the vote. Six percent (6%) prefer another candidate in the race, and 10% are undecided.

That’s little changed from two weeks ago.

Sixty-six percent (66%) of Pennsylvania voters regard Toomey as politically conservative, and 42% place his views in the mainstream. Twenty-seven percent (27%) see him as an extremist, with 31% undecided.
Forty-five percent (45%) feel that Sestak is politically liberal, while 27% characterize him as a moderate. But 39% regard his views an extreme, while nearly as many (37%) think his views are in the mainstream. But roughly one-in-four voters (23%) aren’t sure.

The new survey finds Sestak a point closer to Toomey than he was two weeks ago. While that’s not a significant change, it’s enough to move Pennsylvania from Leans Republican to Toss-Up status in the Rasmussen Reports Senate Balance of Power rankings.
