6) Democrats are casting Richard Mourdock as a bully in a new radio ad buy meant to match (with $20,000 behind it) an ad in Indiana hitting Rep. Joe Donnelly from an outside group launched earlier this month. 5) As expected, Linda McMahon won the state GOP's endorsement in the Senate race -- but don't count on former Rep. Chris Shays quitting; armed with an electability argument (he polls better in general election matchups), he's vowed to press on to the primary. 4) Sen. Jon Tester, D-Mont., is up with his seventh (yes, seventh) TV ad of the campaign, a $60,000 spot about fighting for veterans. Tester's early strategy has been pretty clear: Try to tout accomplishments on specific issues and localize the race before outside groups pour more massive heaps of money at the race tying him to the Obama administration and the culture of Washington. Nationally, Tester is pressing for accountability: The senator says the chair of the CFTC should be fired over his handling of the recent MF Global scandal. This is consistent with his push to try to strike a pose as someone who is tough on Washington figures. 3) The Milwaukee Journal Sentinel endorsed Republican Gov. Scott Walker over the weekend, prompting an outcry from the state Democratic Party. "One need only read the Milwaukee Sentinel editorials AGAINST the Civil Rights Movement and FOR Joe McCarthy to remember how silly and reactionary a news organization can look in the hindsight of the ages," wrote state party chairman Mike Tate. By picking a fight with the paper, the party is only blowing up a story that isn't otherwise that big. Newspaper endorsements are important, but they don't move the needle in a major way. The state party's overreaction is just its latest misstep. Consider that Democrats have bigger concerns: A fundraising disparity, recent polling showing Walker putting some distance between himself from the Democratic Party and reports indicating national Democrats and the Obama campaign were never really warm to the idea of a recall in the first place. 2) He's a fan and strong supporter of President Obama, but Newark Mayor Cory Booker doesn't like a campaign ad that attacks Romney's work at Bain. He made that point clear before a national audience on Sunday. Booker is from a Democratic state but one with a lot of wealthy voters with ties to Wall Street; he also hails from the centrist wing of the Democratic party. His comments on "Meet the Press" Sunday are a reminder of that. 1) While Obama currently enjoys a 2-to-1 cash advantage over Romney, outside groups have helped the former Massachusetts governor narrow the gap in the race for money, according to reports. Obama once held a 10-to-1 advantage over Romney. Indeed, a Politico analysis shows that super PACs, party committees and the campaign supporting Romney have raised about $402 million since the beginning of the election cycle, compared to $340 million for Obama and his backers. Obama is also trailing on the super PAC front, where the group supporting him, Priorities USA, raised about $1.6 million in April, while the group supporting Romney, Restore Our Future, raised about $4.6 million.
