Everything Trump did while campaigning helped the cause. McDonalds and the Garbage truck were extremely smart moves.
I think his campaign will be a model for campaigns going forward, in particular his use of so-called new media. The question will be, can a different candidate pull it off, or was Trump's sheer force of will the key ingredient?
But the election was won, imo, when Klueless Kommie-la said (on the View no less) that she wouldn't change a thing that Warm Oatmeal Brain Biden had done in the last four years.
