Eric Trump mocked for declaring 'the polls are wrong' -- and using boater parade footage as proof

Eric Trump on Thursday tried to buck up his father's supporters -- but ended up getting brutally mocked instead.

In a Thursday afternoon tweet, Trump declared that "the polls are wrong" and posted footage of a Trump boater parade as proof.

The Trump campaign has regularly pointed to boater parades, which often feature supporters who own pricey power yachts, as evidence that they have enthusiasm on their side.

However, as many of Trump's Twitter followers pointed out, the vast majority of Americans do not own a yacht, which means the boater parades are not likely indicative of the president's electoral fortunes.
