4) The pace of the Wisconsin Senate race is starting to pick up. Following the entrance of former Rep. Mark Neumann and the expected run of state Assembly Speaker Jeff Fitzgerald, state Sen. Frank Lasee said on Tuesday he's likely to take the plunge as well. 3) Police said shots fired at the district office of Rep. Gene Green, D-Texas, in north Houston Tuesday likely came from a pellet or BB gun. the Houston Chronicle reports. The shots hit the windows of Green's office, but no one in the office was hurt. 2) Texas Gov. Rick Perry stuck to the talking points during his interview with conservative radio host Sean Hannity on Tuesday afternoon. He barely mentioned GOP opponent Mitt Romney, repeatedly underscored Texas' record on jobs under his watch, and criticized President Obama for not having "wise men and women around him." Meanwhile, the Perry blowback is continuing to churn: The Washington Post op-ed page today features two scathing op-eds about Perry's record in Texas and states' rights musings in his book. Marcus said Perry makes Bush look like "George McGovern" and Milbank portrays the Texas governor as an aspiring theocrat. 1) Romney emerged from his low-key presidential campaign to begin courting voters who have shifted to Perry's camp, the Wall Street Journal reports. Romney will appear with the Tea Party Express in New Hampshire on Labor Day, then appear at a South Carolina candidates' forum that he had previously publicly snubbed. But FreedomWorks is planning to protest Romney's Granite State appearance. Romney also took an indirect swipe at Perry on Tuesday in his home state of Texas, saying "Career politicians got us into this mess, and they simply don't know how to get us out." With aides signaling to the Washington Post earlier this week the modes of attack they are likely to use against Perry and the pace of debates picking up after Labor Day, it may not be long before we see Romney begin to engage with the Texas governor more seriously.
