WEDNESDAY’S CAMPAIGN ROUND-UP….Today’s installment of campaign-related news items that wouldn’t generate a post of their own, but may be of interest to political observers.

* Things continue to not go well for Norm Coleman. On the other hand, he is the only non-senator allowed to attend the Senate Republicans’ weekly caucus meetings.

* Pennsylvania’s Republican Committee Chairman suggested yesterday that the state party may not support Sen. Arlen Specter’s (R) re-election campaign.

* On a related note, Specter expects to have a primary opponent, though it’s not yet clear who that might be.

* In an unusual twist, the U.S. Chamber of Commerce is “praising House Democrats for voting in favor of the economic stimulus measure that passed two weeks ago.”

* Tony Perkins, the very conservative head of the Family Research Council, continues to explore a possible primary challenge against Sen. David Vitter (R) in Louisiana. Perkins served in the state legislature and ran against Vitter in the 2002 Senate primary.

* And Ben Smith has an interesting item on Bobby Jindal, Tim Pawlenty, and Mark Sanford making an appearance earlier this week “at the regular gathering of Legacy, a group of mostly 40-and-under Republicans with roots in Texas but membership across the country. The well-heeled group strives to avoid media attention and does not let reporters attend their meetings.”
