Welcome to our new politics briefing. You can find it Monday through Friday at 5 a.m. and updated throughout the day.

Cracking Trump's wall

It seems part of his plan is to force Mexico to pay for the border fence by threatening to cut off billions of dollars immigrants send home., says the Washington Post.

Just how this could be done brings serious questions. The story links a two-page memo that discusses barring aliens from wiring money outside the U.S. without proving legal status.

The take-away

Newsday columnist Dan Janison finds five ways Donald Trump might keep support from those registered Republicans in his home state. Even here, in the heart of New York’s confrontation belt, growing some manners and stepping outside the protective bubble might help.

Bill's L.I. pitch for Hil

Former President Bill Clinton boasted of his wife's record while "our senator" during an organizing meeting at The Vault on Hempstead Turnpike in Elmont, hailing all she "delivered to New York" even as Republicans controlled Congress. Newsday video is here.

Hillary Clinton is holding a town hall on women’s issues at the Medgar Evers College Gymnasium on Bedford Avenue in Brooklyn. Doors open at 1:30 p.m.

Sanders’ persistence and heckling by his supporters has been frustrating both Clintons as of late. On the money front, Sanders outraised Clinton in March, $44 million to $29.5 million

Kasich’s case

Third-place Republican contender John Kasich told a town-hall forum at Hofstra University that he’s staying in the race even if Donald Trump and Ted Cruz don’t like it.

“I’m dropping in, I’m not dropping out,” said Kasich — the first of the remaining presidential contenders from either party to meet with Long Island voters. (Click here for video.)

Trump complains that the Ohioan “is taking my votes.” Kasich is unstung by the accusation. “I know how to fix these things that Trump voters care about,” such as stagnant wages, he said. “I’m gonna get a heckuva lot of his voters.”

Later, a crowd of 3,000 people at The Paramount in Huntington heard Kasich’s rationale on why the GOP convention in July would turn to him if Trump comes up short. “I need to just get better known, and it’s happening now,” he said. Newsday’s Laura Figueroa and Paul LaRocco report.

Clinton mobilizes, wages war

Hillary Clinton met privately with more than 100 Democratic lawmakers in Albany Monday afternoon, asking them to help rally support in their districts for her New York primary campaign and “take her over the top.”

Earlier, she joined Gov. Andrew Cuomo in Manhattan at the signing of the bill legislators passed to raise the state minimum wage and went after Trump as no friend of labor.

“In fact, Donald Trump has said wages are too high,” Clinton said. (Trump made those remarks in a debate last November.) When someone in the audience shouted that the former host of “The Apprentice” “should be fired,” Clinton responded, “He’s fired. That’s funny.”

Clinton-Sanders debate set

After days of haggling, Clinton and Sanders have agreed to a two-hour debate in Brooklyn on April 14 at 9 p.m. — the same night that all three Republicans in the race are scheduled to attend a GOP gala in Manhattan.

CNN, which will host the debate along with New York City’s cable news station NY1, said it will be held at the Brooklyn Navy Yard’s Duggal Greenhouse. CNN’s anchor Wolf Blitzer and chief political correspondent Dana Bash will be on the moderator panel along with NY1 political anchor Errol Louis.

Bill gets it organized

Former President Bill Clinton will be at an organizing event 11 a.m. Tuesday at The Vault on Hempstead Turnpike in Elmont. Hillary Clinton is holding a town hall on women’s issues at the Medgar Evers College Gymnasium on Bedford Avenue in Brooklyn. Doors open at 1:30 p.m.

Sanders’ persistence and heckling by his supporters has been frustrating both Clintons as of late. On the money front, Sanders outraised Clinton in March, $44 million to $29.5 million.

Cruz: No cheesy apparel

On the final campaigning day in Wisconsin before “America’s Dairyland” holds its primary, Cruz politely but firmly declined to don the cheesehead hat made famous by Green Bay Packers fans. “There is an ironclad rule of politics which is no funny hats,” Cruz said as a Wall Street Journal reporter modeled one and tried to goad the candidate into doing likewise.

The verdict of Wisconsin GOP primary voters could either halt Trump’s momentum or heighten doubts about Cruz’s prospects of catching up, Newsday’s Emily Ngo reports. Polls suggest Sanders is headed for a narrow win over Clinton ahead of their New York battle.

Trump Hog-Called Out

Iowa’s Sen. Joni Ernst said women who support Trump should still make their displeasure known over his tone and say, “I’m not going to put up with his nonsense.”

Ernst is the conservative Republican who won office in 2014 after famously running a TV ad boasting of how she “grew up castrating hogs” on a farm.
