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:
* Mayors Against Illegal Guns has a new ad out today, going after Sen. Marco Rubio (R-Fla.) for his opposition to expanded background checks. In reference to 2016, the spot tells viewers, "Rubio's presidential ambitions make Florida less safe."
* As expected, Robin Kelly cruised to her congressional special election victory last night, winning 74% of the vote in her Chicago-area district.
* Elizabeth Colbert Busch, still hoping to put some distance between herself and her party in her very conservative South Carolina district, quickly denounced President Obama's new budget plan this morning.
* In Louisiana, a Republican-friendly pollster found that Sen. Mary Landrieu (D-La.) has a decent favorability rating in advance of her 2014 re-election race, and leads her likely Republican challenger, Rep. Bill Cassidy (R), by five points, 46% to 41%.
* Former Sen. Rick Santorum (R) has some advice for his party: it would be "suicidal" for Republicans to follow the American mainstream and support marriage equality.
* In Arkansas, former Rep. Mike Ross (D) will kick off his gubernatorial campaign next week, and he'll apparently face former Lieutenant Governor Bill Halter in a Democratic primary. Former Rep. Asa Hutchinson is generally considered the Republican frontrunner.
* In Michigan, Republicans have not yet recruited a top-tier candidate to run for the U.S. Senate, but House Intelligence Committee Chairman Mike Rogers (R) is apparently interested and will announce his plans "within the near future."
* And former Rep. Anthony Weiner (D) is now acknowledging that he's weighing a political comeback and may run for mayor of New York City.
