Jeb Bush thinks Donald Trump would be a worse president than Barack Obama.

“We will be worse off than we are now” with Trump as president, Bush told a crowd in Mount Pleasant, S.C., Wednesday, according to Politico. “And we are pretty bad off right now.” Bush’s broadsides against Trump were the start of the former Florida governor’s all-out offensive against his Republican primary rival ahead of the Feb. 20 South Carolina GOP primary. Bush’s surrogates, meanwhile, are working to bury fellow GOP rivals John Kasich and Marco Rubio. Bush is hoping to resurrect a campaign that seemed on the verge of collapse heading into Tuesday’s New Hampshire primary, in which he finished fourth — just slightly ahead of Rubio.

The terrifying moment that is Trump: Trump won New Hampshire by a wide margin. That victory, and the political rise of the real-estate mogul, has Vox’s Ezra Klein declaring Trump’s ascendancy to be a “terrifying moment in American politics.” A sample of Klein’s piece: “Trump is the most dangerous candidate for president in memory. He pairs terrible ideas with an alarming temperament; he’s a racist, a sexist, and a demagogue, but he’s also a narcissist, a bully, and a dilettante.” Klein concludes by saying there is something “scary” about Trump and the country should fear his rise.

Black lawmakers to Clinton’s aid: The Hill writes African-American lawmakers are closing ranks around Hillary Clinton amid growing fears that Bernie Sanders poses a real threat to her presidential candidacy. The Congressional Black Caucus PAC voted this week to endorse Clinton, and more than a dozen of its members will storm South Carolina later this month to stump for her ahead of the Feb. 27 Democratic primary. A worry for the Clinton campaign is that the former secretary of state could lose her grip on the black vote, a constituency long seen as a firewall in the Democratic primary.

Debate guide: Clinton and Sanders square off for their latest debate on Thursday night in Milwaukee, and National Public Radio has a list of things to watch. Among them: Will they modify their messaging to appeal to African-American, Hispanic and young voters? The first two states to vote — Iowa and New Hampshire — were overwhelmingly white. But that dynamic shifts in Nevada and South Carolina, and for Super Tuesday. NPR says to expect to hear more about the Flint water crisis, criminal justice reform, voting rights and immigration reform.

Tougher North Korea sanctions passed:The Senate unanimously passed legislation that aims to derail North Korea’s drive for nuclear weapons by hitting Pyongyang with more stringent sanctions. As the Associated Press writes, the measure targets North Korea’s ability to finance the development of miniaturized nuclear warheads and the long-range missiles required to deliver them. The House passed a similar bill last month.
