OFF TO THE RACES: Trump up 15 points in Indiana, per new poll

From our latest NBC/WSJ/Marist poll of Indiana, from one of us(!): "Donald Trump holds a 15-point lead over Ted Cruz in the potentially decisive May 3 presidential primary race in Indiana, according to results from a new NBC News/Wall Street Journal/Marist poll. Trump gets support from 49 percent of likely Republican primary voters — followed by Cruz at 34 percent and John Kasich at 13 percent. If that margin in Indiana holds on Tuesday, Trump would be on a glide path towards obtaining the 1,237 delegates he needs to win the Republican nomination on a first ballot at the GOP convention in July."

The big story, from AP: "Back in the part of the country where he last lost to Ted Cruz, Republican presidential front-runner Donald Trump is confidently pushing for a win Tuesday in Indiana that he argues ought to knock the Texas senator out of the race. Buoyed by a sweep of last week's primary elections along the East Coast, the billionaire businessman appears to have learned a few lessons from his defeat last month to the Texas senator in nearby Wisconsin. There have been no slip-ups on talk radio in recent days, nor stumbles over issues that matter deeply to Republican voters. Trump arrived in Indianapolis to start campaigning the day after winning his home-state New York primary weeks ago and began spending money on television advertising far sooner than he did in Wisconsin."

The latest in convention tech, via POLITICO: "Senior party officials — worried about hacking and Internet reliability in the overcrowded Cleveland arena and eager to preserve the live television drama surrounding a drawn-out roll call — are ruling out a change to convention bylaws that would allow for electronic voting on the ballots to select the GOP’s presidential and vice presidential nominees."

CRUZ: In an interview with one of us(!), Cruz refused multiple times to say whether or not he would support Trump if he became the GOP nominee.

From the New York Times writes that delegates - like voters - are showing signs of momentum away from Cruz as the Texas senator loses steam.

"Cruz came to Indiana to try to resuscitate his flagging campaign at a pivotal moment in the Republican presidential race. But with just one day of campaigning left until Tuesday’s vote — and after a series of desperation measures — the freshman senator from Texas is on the verge of a defeat that would ravage his campaign and raise new questions about whether his mission to stop the mogul has become futile," writes the Washington Post.

Why hasn't Marco Rubio endorsed Ted Cruz yet? POLITICO: "Marco Rubio won’t be endorsing Ted Cruz during the Republican presidential primary, but he’s likely to back the Texas senator at a contested convention — if it gets the far. The de facto plan, Rubio’s backers say, is designed to help Cruz. It also, however, protects Rubio's political future, including if he decides to make another run for the White House."

SANDERS: In a press conference Sunday, he insisted he still has a path to the nomination. From Danny Freeman: " Facing a large delegate deficit, tough odds and just 10 remaining state contests, Senator Bernie Sanders made it clear Sunday that he intends to fight on to become the Democratic presidential nominee. Sanders' stated path relies on primary opponent Hillary Clinton's not reaching a majority of pledged delegates and on superdelegates' switching their allegiances."

He raised less than $26 million in April, compared to a $44 million haul in March.

TRUMP: He said that China is "raping" America.

The New York Times did a deeply-reported look over the weekend at who might be open to being Trump's VP.

Heidi Cruz flubbed and called her husband “an immigrant.” Donald Trump wasted little time in picking up on the error.

From POLITICO: "Donald Trump won the New Hampshire primary handily nearly three months ago, but state GOP officials are pushing a plan to block all of Trump's delegates from serving on any of the key committees at the national convention in July. Instead, the coveted convention slots would go entirely to delegates assigned to Marco Rubio, Jeb Bush, John Kasich and Ted Cruz, even though Trump won 35 percent of the vote, more than double his closest competitor."

The Wall Street Journal: "Republican Donald Trump’s large campaign rallies, and the protests around them, are leaving some cities and towns with a big bill. In March, 15 Trump presidential-campaign events cost local authorities more than $300,000 to secure and manage, local police departments and campaign venues reported in a survey by The Wall Street Journal. That is an average of $20,000 in costs per event. Some event sites are billing the campaign for reimbursement, and some have gotten money back."

"Donald Trump has a Plan B if he's faced with a contested convention, and it involves the sort of outside groups that he's called 'corrupt,'" writes the AP. MORE: "Outside groups, including one led by longtime Trump political ally Roger Stone, and a loose collection of colorful supporters such as "Bikers for Trump" are organizing ahead of the July convention in Cleveland. They're soliciting money to pay for their transportation and housing, and they're already trying to influence the mood of the convention with a social media campaign saying that anything short of a Trump nomination would be "stealing."

OBAMA AGENDA: Heading to Harvard

Writes the Washington Post: "The number of cases the justices have accepted has fallen, meaning that a docket that in recent years has been smaller than what is traditional is shrinking still. The court has accepted only six cases since Scalia died Feb. 13. The number is low compared with the average, editor Amy Howe said at an event last week reviewing the Supreme Court’s work. And none of the cases that the court has accepted for the term that begins in October approach the level of controversy that have marked the dramatic rulings of recent years."

Malia Obama is heading to Harvard in 2017.
