Donald Trump might have accidentally lost a lot of voters from his Florida base Tuesday night.

During a Panama City rally, Trump advised his voters to take to the polls and vote for him, just on the wrong day.

He urged voters to get in line and vote for him on Nov. 28, that's 20 days too late.

In Florida, Trump just said Election Day is November 28 — Marina Fang (@marinafang) October 12, 2016

One could speculate that he mixed up the number because just a few sentences prior, he said there are 28 days left until the election.

Perhaps, it was a simple mix up, but he should hope that his supporters confirm Election Day on their calendars.

Trump was right on one thing, though: There are 28 days until this election is over and America can't wait for the campaigns to end.
