Regardless of how accurate or inaccurate it is, I think it's stupid to compare Trump to Hitler.
1) It's a big slap in the face to the millions of people who actually suffered under Nazism. When Trump actually starts ordering mass killings, we can talk. But until then, he's just any other right-wing populist.
2) People who are on the fence probably won't be swayed by clips like this any more than interspersing Sanders speeches with clips historic communists would persuade undecided Democratic primary voters. Not to mention all of the people who honestly really do want an authoritarian running the country (see

3) The thing that will actually dissuade people from voting for Trump aren't his views - people know he says crazy sh**, and it clearly hasn't had much of an impact on his performance so far. People need to see him for the joke he actually is. His campaign talks about him being "in character" when he delivers his "performances." People can rally behind a populist a lot easier than they can rally behind some rich guy playing a demagogue for money and attention.
4) It gives Trump a mystique that he really doesn't deserve, and if anything helps him. Trump isn't a man who can take over a continent by force or even lead an army. He's a mascot for a real estate conglomerate. If you want to undermine his support, compare him to ShamWow guy, not Hitler.
