6) Former Rep. Matt Salmon (R-Ariz.) is running for the seat he once held, he announced Tuesday. Salmon will run for the 6th District seat Rep. Jeff Flake (R) is giving up to run for the Senate. Former state Senate Majority Leader Chuck Gray is already in the GOP race and state Speaker Kirk Adams is also considering running. 5) The House Majority PAC, which was recently launched by a group of Democratic House campaign veterans, is launching its first paid ad campaign Thursday. The ads, which were produced by Shorr, Johnson, Magnus Strategic Media, go after against ten House Republicans who voted for House Budget Chairman Paul Ryan's budget proposal last week. According to those familiar with the effort, in total the effort is a six-figure campaign. One of the radio ads says the proposal will end Medicare and cut taxes "by trillions for the wealthiest Americans and big corporations." The ads will target Reps. Paul Gosar (R-Ariz.), Rick Crawford (R-Ark.), Allen West (R-Fla.), Chip Cravaack (R-Minn.), Charlie Bass (R-N.H.), Ann Marie Buerkle (R-N.Y.), Joe Heck (R-Nev.), Francisco Canseco (R-Texas), Blake Farenthold (R-Texas), and Sean Duffy (R-Wis.). On Tuesday, we reported on the Democratic Congressional Campaign Committee's ad campaign targeting 25 House Members who voted for the Ryan budget. The size of the buy was very low -- in fact the total ad buy was under $6,000 dollars and in some districts, the buy was as low as $40. 4) St. Louis businessman John Brunner (R) told AP on Tuesday he is considering a Senate run in Missouri. Brunner has the ability to self-fund and in the past, has donated about $9,000 to Rep. Todd Akin's (R) congressional campaigns over the past decade. He also given thousands more to other GOP candidates and committees. Akin is also considering a bid. Unimpressive first quarter fundraising numbers from the already declared GOP candidates could make the race a crowded affair. 3) Add the Club for Growth to the list of people and groups unhappy with Sen. Richard Lugar (R-Ind.) Club President and former Indiana Rep. Chris Chocola said Tuesday "we do have some concerns about Senator Lugar and his service. We think it would be probably best if he would retire at this point." 2) Former Minnesota Gov. Tim Pawlenty (R) was in Nevada Tuesday and sat down with Nevada political guru Jon Ralston. Pawlenty met with Republicans in Las Vegas and said he would be willing to reconsider whether Yucca Mountain is a suitable site for the long-term disposal of nuclear waste and also said gambling has a "corrosive" effect on some people's lives, but that legalized gaming is a local issue. 1) Obama will court donors in northern and southern California over the next two days in a big test of whether he can repeat the success he had among the entertainment and tech industries in 2008. Obama will host at town hall at Facebook headquarters in Palo Alto today. Meanwhile, people familiar with the company's plans said talks to hire former White House Press Secretary Robert Gibbs have fallen apart, the Wall Street Journal reports. -- Reid Wilson and Steven Shepard contributed to this post CORRECTION: The original version of this post gave the incorrect name of the candidate running for the House in Arizona.
