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:
* The U.S. Chamber of Commerce is launching its second major ad buy in Kentucky in support of Senate Minority Leader Mitch McConnell (R). The first spot touted McConnell's support for coal; the new one announced yesterday blasts "this Obamacare mess."
* Rep. Rush Holt (D-N.J.) announced his retirement yesterday, just five months after his U.S. Senate bid fell short. Democrats are widely expected to keep his New Jersey seat "blue."
* Speaking of retirements, Rep. Gloria Negrete McLeod (D-Calif.) also announced yesterday she'll leave Congress at the end of the term. The congresswoman, who was elected in 2012, intends to seek local office instead. Her district is also seen as a Democratic stronghold.
* In Mississippi, Sen. Thad Cochran (R) apparently caused a stir on the right yesterday when he told reporters, "The Tea Party is something I don't really know a lot about." The Club for Growth soon after turned the remark into a short online clip.
* The Democratic Senatorial Campaign Committee outraised its Republican counterpart last month, $6.6 million to $4.6 million.
* Former Sen. Scott Brown (R) of Massachusetts, thinking about running again in a different state, is no longer on Fox News' payroll. The Republican signed a one-year contract with Fox News last February, but it expired this month. [Update: The network is now saying the Boston Globe report, which Fox News confirmed yesterday, is untrue, and that Brown's contract has been renewed.]
* And in Hawaii, a new Hawaii News Now/Star Advertiser poll shows incumbent Gov. Neil Abercrombie (D) trailing Duke Aiona (R) in a hypothetical match-up by eight points. A possible wildcard is Mufi Hannemann, who may yet run as a popular independent.
