Today's installment of campaign-related news items from across the country.
* Politico reports that a gathering of Republican financiers is scheduled for next week, "convened by the donor network helmed by hedge fund billionaire Paul Singer, who supports Marco Rubio." The discussion will take place after Tuesday's contests and will "assess big-money general election spending plans."
* The latest Mason-Dixon poll of Florida Democrats shows Hillary Clinton with a big lead over Bernie Sanders, 68% to 23%. Most other polling doesn't show a gap quite that large, though Clinton appears to be the clear favorite in the state.
* In Ohio's closely watched U.S. Senate race, PPP's new survey shows former Gov. Ted Strickland (D) with the narrowest of leads over incumbent Sen. Rob Portman (R), 41% to 40%.
* The same poll found both Clinton and Sanders ahead in Ohio in a general-election race, except against Ohio Gov. John Kasich (R), who would be the favorite in his home state.
* Sen. Dan Coats (R-Ind.) was asked this week whether he believes Donald Trump could be trusted with the nation's nuclear codes. "Well, that's a tough question," the Republican senator replied.
* House Veterans' Affairs Committee Chairman Jeff Miller (R-Fla.) announced yesterday he's retiring at the end of this year, wrapping up 16 years on Capitol Hill.
* Speaking of Florida, two polls this week found Rep. Patrick Murphy leading Rep. Alan Grayson in their Democratic Senate primary by margins of 6 and 11 points, respectively.
* Reuters reports that House Speaker Paul Ryan's (R-Wis.) political operation this week sent a cease-and-desist letter to "a group that is trying to draft him as a Republican presidential candidate, urging it to halt its activities and warning of legal risk."
* And in California, former Rep. Joe Baca is trying to launch a congressional comeback bid, but this time, the former Democrat is running as a Republican. Baca lost as an incumbent in a 2012 primary, and failed again in another Democratic primary in 2014. The California conservative apparently decided switching parties offered more hope.
