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:
* Former Sen. Scott Brown (R-Mass.) has apparently ended his "exploratory" phase, and is now officially running for the Senate in New Hampshire, just two years after losing his seat in Massachusetts.
* Senate Majority Leader Harry Reid (D-Nev.) reminded Brown yesterday, "The Constitution guarantees every state two senators, but it does not guarantee every senator two states."
* Democrats appear to have regained their edge in the congressional generic ballot, but not by much. A new Quinnipiac poll shows Dems leading Republicans, 40% to 38%.
* In Georgia, Republicans are apparently concerned enough about Michelle Nunn's (D) Senate candidacy that they're running attack ads against her. A super PAC called the Ending Spending Action Fund blasts the Affordable Care Act in the new commercial, which Nunn wasn't in Congress to vote for.
* In Washington, D.C., yesterday, incumbent Mayor Vincent Gray, burdened by a federal corruption investigation into his 2010 campaign, lost a Democratic primary fight against Muriel Bowser, a D.C. Council member.
* There's a crowded primary to replace Rep. Ed Pastor (D) in Arizona, but the progressive congressman threw his support this week to Maricopa County Supervisor Mary Rose Wilcox (D), which is expected to help separate her from the pack.
* And in Florida, former Alachua County sheriff Jacob Rush is taking on Rep. Ted Yoho in a Republican primary, which wouldn't ordinarily be especially noteworthy, except for Rush's background as "Chazz Darling" in a community of gothic-punk role-playing gamers. Rush otherwise presents himself to voters as the ultimate "conservative straight shooter."
