Watch Donald Trump Contradict Himself on Every Major Campaign Issue

The Republican nominee’s brutal takedown of…himself.

It’s no secret that Donald Trump, ever the opportunist, has flip-flopped on a number of major campaign issues. But watching the Republican nominee reverse course in real-time is something else.

A new video has neatly compiled numerous clips, many of them preceding Trump’s presidential bid, showing the real estate magnate contradicting himself on everything from abortion to nuclear weapons (and even David Duke!) over the years. It’s perhaps the greatest piece of evidence that Trump is his own worst enemy. Watch above to see his very own words prove to be the strongest case against him.

The person who posted the video to YouTube did not immediately respond to a request for comment.
