Watch: Donald Trump Booed as He Votes in Midtown Manhattan; Eric Trump Tweets Illegal Ballot Picture

Donald Trump exercised his civic duty Tuesday morning and voted at his polling place in Midtown Manhattan.

There's no way to be 100 percent sure whom he voted for (though we have a pretty good guess). We can, though, say this definitively: He was booed furiously by bystanders as he walked inside.

Videos from the scene showed Trump surrounded by Secret Service on a sidewalk blocked off by metal barriers and black cars. Trump flashed a grin and shot a wave to the crowd as he walked through the doors of his designated polling place at PS59 on East 56th street between Second and Third Avenues.

See video of Trump being showered by the lusty boos here:

And after they voted, Trump was laughed at in the hallway as he was exiting the building. One voter waiting in line shouted, "You're gonna lose!" at Trump as he and Melania left.

While at least two of Trump's kids didn't vote in the New York Republican primary because they didn't register to vote in time, at least one registered in time to vote in the general election.

How do we know? Eric Trump tweeted a picture of his ballot.

Taking a photograph in a voting booth is illegal in New York. Eric Trump has since deleted his tweet.

Because this is 2016, though, we have the screenshot to prove it:

Hillary and Bill Clinton cast their votes earlier Tuesday in their hometown of Chappaqua, New York.
