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:
* How can we tell Mitt Romney expects to do poorly tonight? His campaign released a memo this morning saying the results don't really mean anything.
* In a bit of a surprise, former Sen. Bob Kerrey (D) announced this morning that he won't seek a comeback bid in Nebraska this year.
* How racist was Pete Hoekstra's (R) Senate ad in Michigan? Even a lot of Republicans feel comfortable criticizing it.
* Newt Gingrich has been fighting to get his name on Virginia's primary ballot next month, but yesterday, his campaign gave up and scrapped its legal appeals.
* Rick Santorum is not above references to "death panels" in attacking the health care policies of both President Obama and Mitt Romney.
* Speaking of Santorum, he's still struggling to get his name on the primary ballot in Indiana.
* In Ohio, Public Policy Polling shows incumbent Sen. Sherrod Brown (D) with a double-digit lead over his Republican challenger, Josh Mandel, 47% to 36%.
* In Arizona, former Rep. Gabby Giffords (D) will reportedly back Ron Barber as her preferred successor. Barber, a former Giffords aide, was injured during last year's assassination attempt in Tucson.
* And Michele Bachmann, reflecting on her failed presidential campaign yesterday, described herself as "the perfect candidate." She didn't appear to be kidding.
