Obama’s Tangled History With Supreme Court Sets Stage for Nominee Fight

WASHINGTON — The first time President Obama sat down to pick a new Supreme Court justice, surprised aides discovered that he had gone beyond the briefing memos to read the leading candidate’s past judicial rulings. The president, a onetime constitutional law teacher, was in his element, a “legal nerd,” as one aide called him, putting theory into practice.

But if nothing else, the last seven years have made clear to Mr. Obama that the Supreme Court is anything but a nerdy, academic exercise. His currentstandoff with the Senate over replacing Justice Antonin Scalia culminates a profoundly consequential struggle over not just the law, but power, politics and his legacy.

Inside the Republican Party’s Desperate Mission to Stop Donald Trump

The scenario Karl Rove outlined was bleak.

Addressing a luncheon of Republican governors and donors in Washington on Feb. 19, he warned that Donald J. Trump’s increasingly likely nomination would be catastrophic, dooming the party in November. But Mr. Rove, the master strategist of George W. Bush’s campaigns, insisted it was not too late for them to stop Mr. Trump, according to three people present.

At a meeting of Republican governors the next morning, Paul R. LePage of Maine called for action. Seated at a long boardroom table at the Willard Hotel, he erupted in frustration over the state of the 2016 race, saying Mr. Trump’s nomination would deeply wound the Republican Party. Mr. LePage urged the governors to draft an open letter “to the people,” disavowing Mr. Trump and his divisive brand of politics.

Republicans Speed Across South Carolina as Race Tightens

SPARTANBURG, S.C. — The Republican presidential candidates hurtled across South Carolina on Friday to make their final, frantic pitch one day before the state’s primary, as polls showed the race tightening here after a volatile and often nasty week of campaigning.

The vote on Saturday, a critical test of organization and strength for much of the field, comes as the candidates are closing in on Donald J. Trump, who until now has held comfortable leads in the polls here. A new NBC/Wall Street Journal/Marist poll shows Mr. Trump just five points ahead, down from his 16-point lead in the state a month ago.
