As the days tick down to Pennsylvania's May 18 primary, Rep. Joe Sestak has edged ahead of Sen. Arlen Specter for the first time in the race for the Democratic senate nomination, according to a
Muhlenberg College/Daily Call tracking poll conducted May 4-7. The margin of error is 5 points.
Sestak is now in front by 44 percent to 42 percent with 14 percent undecided. When the tracking poll began on May 2, Specter had led 48 percent to 42 percent with 11 percent undecided.
Specter's favorability numbers have gone down somewhat since the start of the tracking poll. He now is seen favorably by 54 percent and unfavorably by 34 percent with 13 percent not sure. On May 2, his favorable-to-unfavorable margin was 58 percent to 31 percent. Sestak has seen a slight rise from a 45 percent to 12 percent favorable-to-unfavorable margin to 48 percent to 13 percent in the new poll. But the biggest difference between Specter and Sestak is the percentage of people who don't know enough about the congressman to be use of their opinion of him, which is 39 percent.

Our New Approach to Comments
In an effort to encourage the same level of civil dialogue among Politics Daily’s readers that we expect of our writers –
a “civilogue,” to use the term coined by PD’s Jeffrey Weiss – we are requiring commenters to use their AOL or AIM screen names to submit a comment, and we are reading all comments before publishing them. Personal attacks (on writers, other readers, Nancy Pelosi, George W. Bush, or anyone at all) and comments that are not productive additions to the conversation will not be published, period, to make room for a discussion among those with ideas to kick around.
