A small plane jetted over the Hudson Friday morning pulling a banner reading "We Outnumber him! Resist!"

The plane was spotted by numerous hawk-eyed New Yorkers and Jerseyites, who quickly reported its existence on Twitter.

In New York City, Hillary Clinton voters outnumbered Trump voters by upward of 1.5 million votes. Nationally, the disparity was around 3 million—the largest popular vote victory by a losing presidential candidate in American history. This fact continues to drive Donald Trump crazy.
