Today's installment of campaign-related news items from across the country.
* Recognizing an opportunity, a pair of anti-Trump groups -- Our Principles PAC and the Club for Growth -- are spending $1.7 million in Wisconsin television advertising in the hopes of slowing Donald Trump's march to the Republican nomination.
* Speaking of Wisconsin advertising, a group supporting Ted Cruz's campaign has made a $500,000 ad buy in advance of the next primary, attacking John Kasich.
* And speaking of Kasich, the editorial board of the Milwaukee Journal Sentinel, Wisconsin's largest newspaper, published an endorsement yesterday supporting the Ohio governor.
* In Public Policy Polling's new national survey, Trump leads Cruz by 10 points, 42% to 32%, with Kasich third at 22%. In a two-man race, however, Trump's lead over Cruz nearly disappears to just two points, 46% to 44%.
* Among Democrats, the same PPP poll shows Hillary Clinton with a big lead over Bernie Sanders, 54% to 36%.
* Speaking of Clinton, the Democratic frontrunner released her first anti-Trump television ad overnight, launching a commercial in New York that slams the Republican's divisiveness and violence.
* And in Pennsylvania's Democratic Senate primary, President Obama and Vice President Biden both officially endorsed Katie McGinty's (D) campaign this morning. It's another setback for former Rep. Joe Sestak (D), who wants a rematch against Sen. Pat Toomey (R).
