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:
* How confident is Rep. Bill Cassidy (R) in Louisiana's U.S. Senate race? Two days before the statewide runoff, the Republican congressman wasn't even in the state campaigning. He'll face off against Sen. Mary Landrieu (D) tomorrow.
* Warren Buffett isn't known for investing much in political campaigns, which made it all the more striking that he contributed $25,000 -- the legal maximum -- to an independent political group gearing up for Hillary Clinton's likely presidential campaign.
* Two years after the Republican National Committee launched an "autopsy" to determine what we went wrong for the party in the 2012 elections, the Democratic National Committee appears to be doing the exact same thing in the wake of the 2014 midterms. Among the notables who'll serve on the DNC's committee are Kentucky Gov. Steve Beshear (D) and former Google CEO Eric Schmidt.
* Florida Democrats are kicking around the idea of pursuing a provocative idea: moving the state's gubernatorial elections so that they coincide with presidential elections. Sen. Bill Nelson (D), who's hinted several times about his gubernatorial ambitions, has said he'd "love" to see the change.
* Outgoing two-term Maryland Gov. Martin O'Malley (D) has not yet launched his presidential campaign, but he's in the process of building an operation. This week, the governor hired Bill Hyers, who most recently managed NYC Mayor Bill de Blasio's (D) campaign, to be O'Malley's campaign manager.
* Speaking of Maryland, former Gov. Bob Ehrlich (R), who lost to O'Malley in 2006 after serving one term, was in New Hampshire this week, and he's apparently kicking around the idea of running for president.
* In Ohio, Sen. Rob Portman (R) bowed out of the 2016 presidential race, but he also received news of a possible, credible Democratic challenger: Rep. Tim Ryan (D) said he's "certainly looking very closely" at taking on the Republican incumbent in two years.
* And in Pennsylvania, former Rep. Joe Sestak (D) came up short in his Senate race against Sen. Pat Toomey (R) in 2010, but he's eager for a rematch in 2016. Roll Call reports, however, that among Pennsylvania Democrats, "some privately question whether he's the party's best bet for a high-stakes Senate race."
