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:
* Both President Obama and Mitt Romney return to the campaign trail today, with scheduled events in Nevada and California. Obama's team, meanwhile, will keep ads off Colorado airwaves for the rest of the week.
* Priorities USA Action, the main pro-Obama super PAC, raised $6 million in June -- less than a third of the haul collected by Restore Our Future, the main pro-Romney super PAC, which raised $20.7 million in June.
* One of the more interesting ads of the month comes by way of Sen. Claire McCaskill (D-Mo.), who launched this spot in the hopes of elevating Rep. Todd Akin (R), whom she sees as the weakest GOP candidate in running against her.
* Speaking of Missouri, the Democratic Governors Association is investing another $500,000 in support of incumbent Gov. Jay Nixon (D), who is favored to win a second term.
* How bad are things for the California Republican Party? It's in danger of shrinking to the rank of a minor party.
* In New Jersey, the latest Quinnipiac poll shows Obama leading Romney by 11 points, and Sen. Bob Menendez (D) leading his GOP challenger by 13 points.
* In a Washington Post op-ed, former Florida Gov. Charlie Crist condemns "zealots" who are "overreacting to contrived threats of voter fraud by significantly narrowing the voting pool."
* And in an unexpected twist, Sen. Tom Coburn (R-Okla.) apparently supports Sen. Joe Manchin's (D-W.Va.) re-election bid, and has donated $250 to the conservative Democrat's campaign.
