Heh. "If the president walked on the Potomac River, tomorrow's headline in the New York Times would be 'President Can't Swim" -- Unknown
Because he'd get to the other side and immediately say, on camera, "I really hate swimming, you know. Swimming is terrible, because it runs down your life battery and water makes you sick. I never drink water."
And then it would come out that he'd illegally re-allocated funds meant for levee building by the Army Corps of Engineers to build a surface-level bridge across the Potomac because he thought it would make for a good photo op. The bridge is destroying marine life along the river and is a hazard to recreational and commercial traffic.
Estimates are that removal and restoral costs, plus existing damage, will run over a billion dollars. The White House decides to leave it in place, and the overwhelming majority of Republican legislators trip over each other in a race to say how awesome it is. Ted Cruz praises President Trump for, "bypassing gridlock to create a desperately needed Potomac pedestrian crossing". After the White House cancels the removal and restoration project, Rand Paul commends President Trump for, "not wasting public money on a vanity project".
Two weeks later a pro-Trump boat parade crashes into the submerged bridge, sinking several boats and requiring extensive rescue efforts by the Coast Guard. Blue posters on Atlas reply to new stories about the disaster by saying "fake news". There are arguments over whether the bridge has turned Virgina into a swing state.
