Today's installment of campaign-related news items from across the country.
* The next primary on the Republican calendar is Wisconsin, which hosts its contest on April 5. An Emerson College poll released yesterday found a very competitive GOP race, with Ted Cruz narrowly leading Donald Trump, 36% to 35%. John Kasich is further back with 19%.
* That same poll found Hillary Clinton with a modest lead over Bernie Sanders among Wisconsin Democrats, 50% to 44%.
* Speaking of Wisconsin, Gov. Scott Walker (R) hasn't formally endorsed any of his former presidential rivals yet, but he made his intentions clear yesterday. "Ted Cruz is the only one who's got a chance other than Donald Trump to win the nomination," Walker said.
* Clinton delivered a speech yesterday at Stanford University on her national security strategy as it relates to ISIS. It represented quite a contrast from what the public heard from the leading Republican candidates the day before.
* Pennsylvania will host a critically important primary in late April, and a new Franklin & Marshall poll shows a tight GOP race. Trump leads Kasich in the survey, 33% to 30%, with Cruz third with 20%.
* The same poll showed Clinton with a big advantage, at least for now, over Sanders among Pennsylvania Democrats, 53% to 28%.
* Speaking of the Keystone State, there's a competitive Democratic Senate primary underway, but the DSCC is no longer neutral: the party committee endorsed Katie McGinty yesterday. The announcement is a blow for former Rep. Joe Sestak (D), who's running again after coming up short in 2010.
* And Rolling Stone magazine, which has featured Bernie Sanders on its cover twice in recent months, endorsed Clinton in its newest issue.
