Today's installment of campaign-related news items from across the country.
* Bernie Sanders hoped to get an additional delegate by requesting a recanvassing of the Kentucky primary results, but the results released yesterday were nevertheless unchanged. In a press statement, the Sanders campaign said it "accepts the results in Kentucky," though it nevertheless complained that the Democratic primary was limited to Democratic voters.
* Donald Trump said yesterday he'd expect a charitable donation of $10 million to $15 million in order to debate Sanders ahead of the June 7 primary in California. The Republican National Committee won't put up that kind of money, but it's nevertheless excited about the possibility of such an event advancing the GOP's interests.
* And speaking of the RNC, Jeff Weaver, Sanders' campaign manager, singled out Republican National Committee Chairman Reince Priebus for praise yesterday during an MSNBC interview.
* In Arizona, the Eagle Forum's Phyllis Schlafy has thrown her support behind Sen. John McCain's Republican primary challenger, Kelli Ward.
* The Koch brothers Freedom Partners Action Fund has purchased $3 million in airtime in Pennsylvania, hoping to boost incumbent Sen. Pat Toomey's (R) bid for a second term.
* In a move that seemed oddly predictable, Martin Shkreli, the 33-year-old former CEO of Turing Pharmaceuticals, has endorsed the Trump campaign.
* Sanders picked up one additional superdelegate yesterday, when West Virginia Democratic National Committeewoman Elaine Harris said she would vote in line with the state's primary voters.
* And FiveThirtyEight published an analysis yesterday of whether the race for the Democratic nomination is "rigged." It concluded that it isn't. What's more, the FiveThirtyEight analysis found that even if every primary and caucus was open to independent voters -- one of the more common concerns raised by Sanders and his supporters -- Hillary Clinton would still prevail.
