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:
* In advance of his presidential campaign, New Jersey Gov. Chris Christie's (R) home-state support continues to drop. A new Quinnipiac poll shows the Republican governor with a 46% approval rating, while 50% disapprove. The pollster's report noted this is Christie's "worst overall score in almost four years."
* Vice President Biden's name is often left out of conversations about the 2016 presidential race, but he told NBC's Matt Lauer this morning he believes he "could do a good job" as a candidate and there's "a chance" he'll throw his hat into the ring.
* This week, Mitt Romney said climate change is a "real and a major problem." For those keeping track, that means the former governor has flip-flop-flip-flopped on the issue, repeatedly changing his mind about the crisis.
* Mike Huckabee's new presidential campaign hasn't begun just yet, but he's already confronting a controversy: his political action committee, ostensibly created to contribute campaign money to like-minded candidates, directed "a significant portion" of its funds to Huckabee's "family members or the coffers of direct-mail fundraising firms."
* In Pennsylvania, Public Policy Polling shows Sen. Pat Toomey (R) with a modest lead over former Rep. Joe Sestak (D), 40% to 36%, in a hypothetical rematch of their 2010 race.
* On a related note, Sestak isn't the only Pennsylvania Dem who's interested -- former Rep. Chris Carney (D) has also said he's "weighing" whether to enter the Senate race. Carney was a member of the Blue Dog Coalition, made up of conservative Democrats.
* And in Nevada, Republicans hope to line up a top-tier challenger for Senate Minority Leader Harry Reid (D) next year, and former Nevada Lt. Gov. Brian Krolicki (R) has expressed an interest.
