A new poll shows a large percentage of voters have yet to choose a candidate in the Pennsylvania Senate race.
Republican Pat Toomey remains out front of Democrat Joe Sestak, but 14 percent of likely voters said they're undecided in a new Allentown Morning Call/Muhlenberg College poll released Tuesday.
Toomey led by 7 points, taking 45 percent of the vote to 38 percent for Sestak. A McClatchy-Marist poll released last week showed Toomey leading the Democrat 51 percent to 42.
Democrats clearly believe this race is still winnable. President Obama travels Sunday to Philadelphia for an event with Sestak. Obama's visit, however, could be a mixed blessing. Of those surveyed, 52 percent said they disapprove of his job performance.
The Morning Call/Muhlenberg College poll surveyed 577 likely voters and was conducted between Sept. 28 and Oct. 4. It has a margin of error of plus or minus 4 percent.
Meanwhile, Sestak's campaign announced a major fundraising haul in the third quarter. Sestak raised more than $3.2 million between July 1 and Sept. 30, his campaign announced Tuesday. His campaign did not reveal its cash on hand and Sestak's new Federal Election Commission report has yet to be made available online. Toomey, meanwhile, said he raised $3.8 million -- topping Sestak by more than a half million dollars in the last quarter.
