By a margin of nearly 2 to 1, Pennsylvania Democrats say that new convert Sen. Arlen Specter should be challenged in next year's primary, according to a new survey by Susquehanna Polling & Research. They want choice.

Sixty-three percent of those surveyed said Specter should face a challenge, 28 percent believed that the five-term incumbent should be the Democratic nominee, and 9 percent were undecided in the poll, which was conducted May 26 to 30. Margin of error for the interviews with 364 Democrats is 5 percentage points.

It could be a reflection of the natural inclination in American consumer-political society to favor choice, or it could reflect annoyance with Democratic leaders in Washington who embraced the former Republican senator and declared he should be renominated. Time will tell. Other polls with head-to-head matchups between Specter and potential challengers, however, have showed Democratic voters favoring Specter by wide margins.

Here is a release with the poll results, plus some other interesting numerical catnip for politics fans.
