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:
* With NRA-backed recall elections coming up in Colorado, state Senate President John Morse (D) is launching this minute-long ad, as reported by Colorado Pols yesterday.
* In Kentucky, Public Policy Polling conducted a stunning new statewide poll for the Progressive Change Campaign Committee and Democracy For America, and found Kentucky Secretary of State Allison Lundergan Grimes (D) narrowly leading Senate Minority Leader Mitch McConnell (R), 45% to 44%.
* Hoping to lower tensions, Sen. Rand Paul (R-Ky.) invited New Jersey Gov. Chris Christie (R) to have a beer with him. The governor declined, saying he's too busy.
* If the 2016 presidential election came down to Paul and former Secretary of State Hillary Clinton, who would Sen. John McCain (R-Ariz.) vote for? It would be "a tough choice," McCain said.
* In West Virginia, Republicans have apparently convinced state Sen. Evan Jenkins to switch parties, abandon Democrats, and run against Rep. Nick Rahall (D) in the state's 3rd congressional district next year.
* Following a series of embarrassing failures in 2012, conservative super PACs have reportedly struggled to raise funds over the first half of 2013. Karl Rove's attack operation, American Crossroads, raised $1.86 million, which isn't much by Crossroads standards, and which would have been far less were it not for a $1 million check from Contran Corp., the holding company of Dallas billionaire Harold Simmons.
