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:
* Rep. John Dingell (D-Mich.) announced this week that he'll retire at the end of this Congress, after more than a half-century on the Hill. Yesterday, however, we learned that his wife, Debbie Dingell, chair of the Wayne State University Board of Governors, intends to run to succeed him.
* In Pennsylvania, a new Quinnipiac poll shows 55% of state voters believe Gov. Tom Corbett (R) hasn't earned a second term. In hypothetical match-ups, the governor trails all six of his would-be Democratic opponents, in margins ranging from 3 to 19 points.
* In Kansas' suddenly interesting Republican U.S. Senate primary, Milton Wolf was already reeling after his recent X-ray controversy, but things got worse yesterday when Alliance Radiology, where Wolf is a partner, was accused of running an illegal "price-fixing scheme."
* In Maryland, the latest Washington Post poll shows Lt. Gov. Anthony Brown (D) with a big lead in the state's Democratic gubernatorial primary, leading Douglas Gansler by a two-to-one margin.
* On a related note, the latest Baltimore Sun poll found nearly identical results. Larry Hogan is leading the Republican primary.
* Republicans are confident about flipping the U.S. Senate seat in West Virginia, but EMILY's List has a poll showing a competitive race, with Rep. Shelley Moore Capito (R) leading Secretary of State Natalie Tennant by only six points, 45% to 39%.
* And Matt Miller, a former official in the Clinton White House and a Washington Post columnist, has decided to run for Congress, hoping to succeed Rep. Henry Waxman (D) in California.
