Thursday's Campaign Round-Up, 5.7.15

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:
* Sources confirmed to msnbc that Hillary Clinton "is directly helping a super PAC supporting her presidential candidacy," holding meetings this week in California with "donors to Priorities USA, the main super PAC that supported President Obama's re-election bid and is now backing Clinton."
* In New Hampshire, a new WMUR poll shows Jeb Bush leading the Republican presidential field with 15% support, followed by Marco Rubio with 12%, and Scott Walker with 11%. Chris Christie has seen his support collapse in the Granite State, dropping from 9% to 3%. The same poll found New Hampshire Republicans consider Christie the least honest candidate -- the New Jersey governor fared slightly worse than Donald Trump.
* Florida Republicans finally have at least one U.S. Senate candidate for 2016: far-right Rep. Ron DeSantis, a Tea Party favorite currently in his second term. The congressman announced his Senate candidacy yesterday morning.
* There are plenty of sitting governors and senators running for president this year, and Mike Huckabee argued on ABC yesterday that each of them should resign their current posts: "[I]t's not that I'm going after anybody. I'm speaking the obvious. If a person has a job that the taxpayers are paying for, shouldn't that person do that job?"
* Rand Paul's political operation reportedly paid $100,000 recently for the domain name. The purchase was made shortly before the Republican senator launched his presidential campaign.
* Rick Santorum hasn't made any effort to hide his presidential ambitions, and the former Republican senator will reportedly launch his national campaign on May 27 in Pittsburgh. It will be his second attempt, following a failed 2012 bid.
* And PPP's latest survey in Arizona suggests the Grand Canyon State may be a 2016 battleground despite its Republican history. In hypothetical match-ups, Hillary Clinton was within a few points of most of the leading Republican candidates. Arizona has only voted Democratic at the presidential level once in the last 60 years.
