OFF TO THE RACES: Big nights for Clinton, Trump
Our NBCNews.com lede overnight: "Clinton, Trump pad leads after nearly clean sweep of rivals"
Here's Benjy Sarlin: "Trump Wins Big, But Nomination Not Guaranteed"
And NBC's Perry Bacon Jr. notes that a week of controversy again didn't stop Trump.
Is Bernie Sanders out of steam? NBC's Alex Seitz-Wald reports.
Alex Jaffe takes a look back at the end of Marco Rubio's campaign.
The big picture, from the New York Times: "The victories were lopsided. The celebrations were effusive. The delegates were piling up by the hundreds. But Donald J. Trump and Hillary Clinton's resounding triumphs on Tuesday masked a profound, historic and unusual reality: Most Americans still don't like him. Or her."
From POLITICO: "The donors who pumped millions into an anti-Trump campaign are now assessing whether to continue the fight. And while some mainstream Republicans are girding for a likely floor fight at the July convention, others are losing their resolve."
CRUZ: He's suggesting Kasich should drop out to make it a two-man race. (But it's hard to do that after he won a state and you didn't…)
KASICH: The New York Times' take on the Ohio governor's victory. "Mr. Kasich must now strain for a larger role in a Republican contest in which he has largely competed in obscurity. In his Tuesday night speech, he did not take on Mr. Trump by name, but said he would carry his own message of uplift "all the way to Cleveland."
The Cincinnati Enquirer front page: "KASICH, FINALLY."
RUBIO: The Miami Herald's Rubio obit: "He'd had little room for error from the start. Rubio boasted no voter base, no donor base and no clear path to the nomination. He'd disturbed Florida's political order by running in the same year as former Gov. Jeb Bush — a decision that angered some Bush loyalists so much they branded Rubio "Judas." To have a shot, Rubio would need a little luck — and a near-flawless campaign."
The Washington Post: "Years of carefully laid plans to repackage the Republican Party's traditional ideas for a fast-changing country came crashing down here on Tuesday when Sen. Marco Rubio suspended his campaign for the presidency after a crippling defeat in his home-state primary."
And from POLITICO: "Rubio's strategy was always an inside straight—overly reliant on a candidate's ability to dominate free national media in order to outperform, outwit and eventually outlast a wide field of rivals. It was sketched out by an inner circle of advisers who believed they could eschew the very fundamentals of presidential campaigning because they had a candidate who transcended. That's exactly what happened in 2016; it just turned out Rubio wasn't the one transcending."
OBAMA AGENDA: The SCOTUS fight is about to begin
Driving the day: "President Obama has made up his mind. The president will announce his nominee to the Supreme Court at 11 a.m. ETWednesday, just over a month after the death of conservative jurist Antonin Scalia left a vacancy on the bench."
The New York Times, on the pick: "White House officials declined to say whom Mr. Obama had chosen, but the president was said to have focused on several sitting judges who have already won approval from Democratic and Republican lawmakers. Among the finalists are the federal appellate judges Sri Srinivasan, Merrick B. Garland and Paul Watford."
