Today’s installment of campaign-related news items that won’t necessarily generate a post of their own, but may be of interest to political observers:

* As strange press stunts go, Sarah Palin’s “One Nation” bus tour is nothing short of bizarre, even for her. Reporters are well aware of this, but keep chasing the bus anyway.

* Former Massachusetts Gov. Mitt Romney (R) finally took his campaign to Iowa on Friday. He immediately endorsed ethanol subsidies, as is required by state voters.

* As of today, Wisconsin’s Governmental Accountability Board will have approved recall elections targeting six Republican state senators.

* Speaking of Wisconsin, it appears that JoAnne Kloppenburg will no longer contest her narrow state Supreme Court defeat.

* In Illinois, the redistricting process will put as many as six congressional Republicans in a far more difficult position for re-election next year. This, in turn, may further complicate GOP efforts to hold onto the party’s House majority.

* Rep. Michele Bachmann (R-Minn.) hasn’t formally kicked off her strange presidential campaign yet, but she’s “very close” to making her announcement.

* And in Texas, the Republicans’ U.S. Senate primary field continues to grow, with state Sen. Dan Patrick announcing his campaign on Laura Ingraham’s radio show. Texas Lt.Gov. David Dewhurst is still considered the frontrunner in the primary.
