A Washington rally that will be hosted by Fox TV’s Glenn Beck and feature conservative power broker Sarah Palin drew the wrath on Friday of the chairman of the House Democratic campaign committee.

USA/Chris Van Hollen rejected organizers’ assurances that the “Restoring Honor Rally” — expected to draw thousands of members of the conservative Tea Party movement — would be “non-political.”

In fact, Van Hollen predicted the rally would be partisan and could turn off many voters.

The event, to be held on Saturday on the National Mall — between the U.S. Capitol and Lincoln Memorial — is billed as an opportunity to “celebrate America by honoring our heroes, our heritage, our future.”

But with Beck and Palin on stage before a crush of enthusiastic followers, the rally seems ripe for partisan bashing.
