You forgot to note that US voters do not directly elect the president or the vice president; instead they choose "electors", who usually pledge to vote for particular candidates.

Speaking of voters, over the past month, we have noticed the lack of presidential candidate posters in yard & billboards. The few we have noticed, they are primarily 1' x 1.5' yard signs. Ditto for Trump, but generally he has larger signs. There are far more, & larger state & local election signs, which is something I've never seen before. 

Even the NYT noticed it, "Where the Trump Name is Emblazoned: The Front Yard"
