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:
* On the generic congressional ballot, a new CNN poll shows Democrats leading Republicans by four among registered voters, 48% to 44%. Among all respondents, the Dems' lead is a little bigger, 48% to 42%.
* In a bit of a surprise, the U.S. Chamber of Commerce intends to support Sen. Mary Landrieu's (D) re-election campaign in Louisiana. The business lobby is nearly always closely aligned with Republicans.
* In Iowa's closely watched U.S. Senate race, where Rep. Bruce Braley (D) has lost his lead against right-wing state Sen. Joni Ernst (R), the Democrat shook up his campaign team late last week, replacing his pollster and admaker.
* With two weeks remaining before Hawaii's Democratic U.S. Senate primary, the League of Conservation Voters hopes to boost appointed Sen. Brian Schatz (D), launching a $380,000 TV ad buy. Schatz faces a tough fight against Rep. Colleen Hanabusa (D).
* In Florida, Gov. Rick Scott (R) recently refused to take a stand on climate science, telling reporters, "I'm not a scientist." His rival, former Gov. Charlie Crist (D), said over the weekend, "I'm not a scientist either but I can use my brain and I can talk to one." Crist made the comment before attending a presentation on global warming by Professor Jeff Chanton of Florida State University's Earth and Atmospheric Science Department.
* In California, Gov. Jerry Brown (D) continues to look like a safe bet for re-election, with a Public Policy Institute of California poll showing the incumbent leading Neel Kashkari (R), 52% to 33%.
* And in South Carolina, where Gov. Nikki Haley (R) is running for a second term, a Palmetto Politics poll shows the incumbent governor with a modest, four-point lead over Vincent Sheheen (D) when independent and libertarian candidates are in the mix. In a head-to-head match-up, however, Haley leads her Democratic challenger by 13 points.
