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:
* It's primary day in Nebraska and West Virginia, and there are U.S. Senate primaries in both states.
* In 2012, the top two Republican Senate candidates in Nebraska ended up beating each other to a pulp, clearing the way for the third candidate, then-state Rep. Deb Fischer, to sneak by both of them. Will history repeat itself in 2014?
* As Rachel noted on the show last night, Clay Aiken's primary opponent died unexpectedly in North Carolina yesterday. It appears, then, that Aiken will be the Democratic nominee to take on Rep. Renee Ellmers (R) this fall. Given the district makeup, Ellmers is considered the favorite.
* In Colorado, PPP shows a tight Senate race, with incumbent Sen. Mark Udall (D) still leading Rep. Cory Gardener (R), but only by four points, 47% to 43%.
* In Hawaii's Democratic Senate primary, most recent polling shows a very fight contest, but PPP now shows appointed Sen. Brian Schatz with a 15-point advantage over Colleen Hanabusa, 49% to 34%.
* The Democratic Senatorial Campaign Committee may not have the kind of money the Koch-financed AFP has, but the party is nevertheless making a considerable investment in Alaska, making a $3.5 million ad buy in support of Sen. Mark Begich (D).
* In Arkansas, term limits prevent Gov. Mike Beebe (D) from seeking a third term, but it's worth noting he has a stunning 79% approval rating in what's generally considered a deep red state.
* And as expected, Kansas election officials will not bar Sen. Pat Roberts (R) from the ballot of residency questions.
