It really sucks that you're right but this is a big part of the reality of modern elections. What people don't seem to get about what you're saying is that this strategy is not intended to make Republicans vote for Democrats, it's intended to make them stay home. Their perception of Trump is that he's a strongman. It doesn't matter that such a description is hilariously off base. It matters that they believe it. Stand up there and call him a pussy with small hands who can't swing a golf club to save his life and watch him throw a toddler fit while the country looks on. This has the added benefit of giving idiotic "undecideds" the soundbites they clearly want which just might convince some of them to vote for you.

Is it stupid? Absolutely. Would it work? I honestly think it would.
