In June, more than 1,000 boats formed a flotilla of Trump supporters that stretched out for eight miles along Florida’s Intracoastal Waterway near Mar-a-Lago, many of them flying “Trump 2020: No More Bullshit” flags. And earlier this month, Donald Trump Jr. invited his Facebook followers to join him in a boat parade off the Hamptons in Long Island organized by Boaters for Trump and led by a 63-foot sportfishing yacht named Team Deplorable.
