Today’s installment of campaign-related news items from across the country.
* According to the official delegate tallies from NBC News and the Associated Press, Donald Trump has now officially secured the necessary number of delegates to be the Republican Party’s presidential nominee.
* Bernie Sanders’ campaign may not be supporting any state Democratic parties, but it is supporting a growing number of specific like-minded candidates. After endorsing and raising money for four congressional candidates, Team Sanders announced earlier this week that it’s also supporting eight down-ballot candidates, and this morning, it threw its backing behind former Sen. Russ Feingold (D), who’s trying to make a comeback in Wisconsin.
* In California, a new poll from the Public Policy Institute of California found Hillary Clinton narrowly leading Bernie Sanders ahead of the state’s June 7 primary, 46% to 44%.
* United Autoworkers, one of the nation’s larger labor unions, officially endorsed Clinton late yesterday.
* The public learned through an accidentally sent email that the Trump campaign is eager to attack Clinton over the discredited Whitewater controversy from 23 years ago.
* In North Carolina, PPP shows Trump with a very narrow lead over Clinton, 43% to 41%.
* On a related note, the same poll shows incumbent Sen. Richard Burr (R) with a three-point lead over Deborah Ross (D), 39% to 36%, while Libertarian Sean Haugh (L) is third with 8%.
* And Sen. Barbara Boxer (D-Calif.) said she was concerned about her security during the recent unrest at the Nevada Democratic Convention. This week, Jeff Weaver, Bernie Sanders’ campaign manager, argued he believes Boxer might have been lying.
