“President Trump appeared unnerved as Joe Biden secured the endorsement of the top firefighters’ union, issuing Monday a string of four tweets targeting the Democratic presidential candidate and union leaders,” CNN reports.

“That’s exactly the behavior several of the President’s political advisers have been warning him against, wary that Trump will elevate a potentially formidable rival.”

President Trump’s re-election campaign manager, Brad Parscale, told CBS News that the campaign had sold almost a million MAGA hats.

Said Parscale: “We’re closing in on selling our one millionth red MAGA hat. You know those are 45 bucks a piece. You do the math there really quick, it’s $45 million. So those kind of things—this president has changed the game in the way merchandise, rallies, the entire experience of being part of the political movement. He’s changed it.”

New York Magazine: “The candidates who had long cultivated relationships with Wall Street — such as Cory Booker and Kirsten Gillibrand — were struggling to gain traction and had grown more hostile to finance as their party had, too. Biden, leading in early polls, had a comforting history in the Obama White House and a reputation as an Establishment Democrat but had never, until a few months ago, maintained any meaningful relationship with Wall Street, hadn’t even announced his candidacy yet, and struck many bankers as a dubious bet to beat Trump.”

“Nearly everyone else in the field, the financiers felt, was being pulled leftward by Bernie… and Elizabeth Warren (less crazy, Democrats on Wall Street think, and way more competent).”

Said one banker: “She would torture them.”
