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 a bit of a surprise, Sen. Marco Rubio (R-Fla.) told a conservative radio host yesterday that he'll either run for president in 2016 or run for re-election to the Senate, but he won't do both. Sen. Rand Paul (R-Ky.) has urged Kentucky's legislature to change state law, allowing him to pursue the opposite course.
* Some Democrats in competitive 2014 races aren't eager to be seen with President Obama, but that's definitely not the case in Michigan, where Rep. Gary Peters, the Dems' U.S. Senate hopeful, eagerly embraced the president in the Wolverine State yesterday.
* In Mississippi, state Sen. Chris McDaniel, who's challenging Sen. Thad Cochran in a Republican primary, was scheduled to appear alongside a racial-segregation advocate at an upcoming gun-rights event. Yesterday, McDaniel cancelled.
* Speaking of awkward associations, Kentucky's Matt Bevin, who's challenging Senate Minority Leader Mitch McConnell in a Republican primary, recently appeared at an event to support cockfighting, though he apparently thought he was speaking at a "states-rights rally."
* In Georgia, Senate hopeful David Perdue (R), who leads in some polls, took an unusual shot at one of his primary rivals, former Georgia Secretary of State Karen Handel (R), for only having a high-school degree. Perdue suggested the nation's challenges are "so complex" that Handel's lack of education is a disqualifier.
* Speaking of Georgia, Senate hopeful Michelle Nunn (D) is launching her first commercial of the year, which features a photo of her with former President George H.W. Bush.
* And in Alaska, Senate hopeful Joe Miller (R) told WorldNetDaily, a fringe conspiracy website, that he'd like to see the United States seize eight Arctic islands that currently belong to Russia.
