The premise here is simple.
If you are NOT voting for Trump, why are you doing so???
The premise makes NO assumption as to who you are voting for or if you intend to abstain from voting. You could be voting Democratic, Constitution, Libertarian, Green, Socialism & Liberation, etc.
The only premise is that you are NOT voting for Trump.
To keep things somewhat neutral, I will NOT express an opinion in the OP, but will wait to a later post.
