Today's installment of campaign-related news items from across the country.
* In a move that would have been very difficult to predict a year ago, Jeb Bush endorsed Ted Cruz's presidential campaign this morning.
* On a related note, the political arm of the Club for Growth, has also formally endorsed Cruz. It's the Club for Growth PAC's first-ever presidential primary endorsement.
* In case anyone believed the Republican presidential race needed more school-yard taunts, Cruz and Donald Trump traded barbs last night related to their respective wives.
* Hillary Clinton picked up another key endorsement from labor late yesterday, when the American Nurses Association announced its support for the Democratic frontrunner.
* A new Quinnipiac poll found Trump leading Cruz, 43% to 29%, among Republicans nationally. John Kasich is further back at 16%.
* The same Quinnipiac poll found Clinton leading Bernie Sanders nationally, 50% to 38%.
* In North Carolina, PPP found a competitive U.S. Senate race taking shape, with incumbent Sen. Richard Burr (R) leading Deborah Ross (D) by just five points, 40% to 35%. Libertarian candidate Sean Haugh was third in the poll with 7%.
* That same PPP poll pointed to an even more competitive gubernatorial race, with incumbent Gov. Pat McCrory (R) up by just two over state Attorney General Roy Cooper (D). 42% to 40%. Libertarian Lon Cecil is third with 6%.
* And in New Hampshire, Senate hopeful Jim Rubens, running against Sen. Kelly Ayotte in a GOP primary, argued yesterday that the terrorist attack in Brussels is the "direct" result of Hillary Clinton's foreign policy. Good to know.
