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:
* To the surprise of no one, Sen. Thad Cochran's (R-Miss.) campaign is airing a new television ad targeting primary rival Chris McDaniel over the recent scandal involving the break-in at Cochran's wife's nursing home.
* In Texas' run-off primaries, 91-year-old Rep. Ralph Hall's (R) career came to an end, losing to Tea Party lawyer John Ratcliffe. Hall will be the last World War II veteran to serve in Congress.
* In Michigan's closely watched U.S. Senate race, a new EPIC-MRA poll shows Rep. Gary Peters (D) leading Terri Lynn Land (R) by six, 44% to 38%. The last survey from the same pollster showed Land up by three.
* In related news, the results were better for Michigan Republicans in the gubernatorial race, where the EPIC-MRA poll found incumbent Gov. Rick Snyder (R) with a nine-point advantage over Mark Schauer (D), 47% to 38%.
* In Wisconsin, the Koch-financed Americans for Prosperity is poised to invest another $900,000 in support of Gov. Scott Walker's (R) re-election campaign. Recent polls show a very tight gubernatorial race in the state.
* Things are looking up for Rep. Jack Kingston's (R) Senate campaign in Georgia. Though he finished second before the run-off primary, the 22-year House member leads David Perdue in a statewide poll and will get an endorsement from Karen Handel, who finished third in the primary.
* A new statewide poll in Hawaii shows a competitive Democratic Senate primary, with appointed Sen. Brian Schatz enjoying a modest lead over Rep. Colleen Hanabusa, 44% to 39%. The primary is not until Aug. 9, and the winner is expected to win in November.
* Rep. Michael Grimm (R-N.Y.), facing a 20-count federal criminal indictment, has decided to blame the media for his troubles.
