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:
* A new Washington Post/ABC News poll shows President Obama and Mitt Romney tied at 47% among likely voters. (Among registered voters, they're also tied at 46% each.)
* Two new polls from Public Policy Polling show Obama leading Romney in Virginia and North Carolina, but by very different margins. The president's lead in Virginia is eight points (50% to 42%), but only one point in North Carolina (47% to 46%).
* Karl Rove's attack operation, Crossroads GPS, is launching another $2.5 million worth of ads, this time focusing on U.S. Senate campaigns. Nearly half of the money will be targeted against Sen. Sherrod Brown (D) of Ohio.
* The Republican primary in Missouri's U.S. Senate race is getting heated, with Sarah Steelman launching this new attack ad targeting her primary opponent, John Brunner.
* As of this morning, Sen. Rob Portman (R-Ohio) is being vetted as a possible Romney running mate, but South Carolina Gov. Nikki Haley (R) is not.
* Rep. Shelley Berkley's (D) Senate campaign in Nevada was dealt a blow yesterday when the House Ethics Committee launched an investigation into whether she helped a kidney transplant program at University Medical Center in Las Vegas because her husband works there.
* In New York yesterday, Rep. Charlie Rangel's (D) primary challenger, State Sen. Adriano Espaillat, finally conceded.
* And in Arkansas' 3rd congressional district, Democrat Ken Aden was forced to withdraw after questions arose about whether he exaggerated his military service record. Aden was running to take on freshman Rep. Steve Womack (R).
