Today's installment of campaign-related news items from across the country.
* Former Vice President Joe Biden released his state and federal tax returns from the last three years yesterday. The materials show the Delaware Democrat making millions from book sales and speaking engagements since leaving office in 2017.
* In North Carolina's 3rd congressional district, state Rep. Greg Murphy (R) won a Republican primary runoff and is now a heavy favorite to replace the late Rep. Walter Jones (R) in Congress.
* Retired Marine fighter pilot Amy McGrath (D) raised more than $2.5 million in the first 24 hours of her U.S. campaign against Sen. Mitch McConnell (R) in Kentucky. That's a presidential-campaign-level haul.
* Billionaire activist Tom Steyer, the latest candidate to launch a Democratic presidential campaign, has a lot of ground to make up, which is why his day-old campaign has launched a $1.4 million ad buy. (His ads will appear on MSNBC, among other outlets.) As Politico noted, this is "the largest single television ad buy in the Democratic presidential primary."
* Former Rep. Bobby Schilling (R) served one term in Congress representing Illinois' 17th congressional district before losing his re-election bid in 2012. His comeback bid in 2014 also fell short. Now, however, Schilling has moved to the other side of the Mississippi River and yesterday kicked off a new congressional campaign in Iowa's 2nd district.
* As Democrats prepare for the possibility of a competitive Senate race in Kansas, former Gov. Kathleen Sebelius (D) announced she won't run for the seat, while former U.S. Attorney Barry Grissom (D) said he is running. Party leaders have also spoken to state Sen. Barbara Bollier (D), a former Republican who switched parties last year, about the race.
* And the Democratic National Committee announced yesterday that the third presidential primary debate will be held in Houston in mid-September. The participation standards will be more difficult, and it's possible there will only be one debate on one night, instead of back-to-back events.
