Today's installment of campaign-related news items from across the country.
* The Wisconsin primary appears to be moving in Ted Cruz's direction, but a pro-Trump super PAC is nevertheless making a seven-figure ad buy in support of the New York Republican. The investment will be in support of this spot.
* And speaking of Badger State advertising, the Cruz campaign yesterday launched a new ad featuring an endorsement from Wisconsin Gov. Scott Walker (R), who remains fairly popular among his Republican constituents.
* In still more Wisconsin news, PPP's latest survey in the state found former Sen. Russ Feingold (D) leading incumbent Sen. Ron Johnson (R), 49% to 39%, in their closely watched rematch.
* There was some chatter this week about whether Bernie Sanders' name would appear on the ballot in June's D.C. primary, but with the Clinton campaign's blessing, it appears local officials are going to fix the problem.
* Add the Pew Research Center to the list of polls showing President Obama's approval rating reaching a three-year high.
* Arizona Gov. Doug Ducey (R), who was elected thanks to extensive support from "dark money" groups that keep their donors secret, yesterday changed state law to make it even easier for these shadowy groups to spend money in statewide elections, including ballot measures.
* A super PAC supporting John Kasich's campaign launched an odd ad yesterday showing Ted Cruz's nose growing as he tells falsehoods.
* And while literally zero congressional incumbents have lost primary challenges this year, Rep. Renee Ellmers (R) is facing a tough fight in North Carolina, and opponents of abortion rights are rallying behind Rep. George Holding (R), who's challenging Ellmers under the state's newly redrawn district map. Their primary is June 7.
