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:

* In case you missed it, Michele Bachmann ended her presidential campaign less than an hour ago.

* Will Rick Perry be the next candidate to quit? Last night, that looked pretty likely, but this morning on Twitter, the Texas governor said he’s ready to get back on the campaign trail and head to South Carolina. If true, this is great news for Mitt Romney, who needs Perry to help split the anti-Romney vote.

* Bill Kristol last night urged Perry to bow out, saying on Fox News, “I just think his dignity I think will suggest to him that he get out.” Perry may have less dignity than Kristol realizes.

* Romney’s campaign is already looking ahead, and will begin airing its first television ads in Florida today, as part of an ad buy worth at least $825,000. No other candidate is on the air in the Sunshine State.

* In Nevada, Romney has already locked up the support of much of the GOP establishment, but Jon Ralston reports this morning that Rick Santorum has finally begun hiring staff in the state.

* In Utah, Sen. Orrin Hatch now has his first Republican primary challenger, with state Sen. Dan Liljenquist kicking off his campaign yesterday.

* Republicans caught a break in the state of Washington with a redistricting commission’s map of the post-census congressional boundaries.

* And on a related note, West Virginia’s congressional map is unresolved, and may be sent to a federal court for review.
