1. Trump is fighting the "Deep State" to the point that "it" will do anything to keep him from being President.
2. Thus, the last election was rigged (despite Trump being in the highest office at the time).
3. The solution is to vote for him again this election ... whose system hasn't changed since the last election.
... If the election was rigged so that Biden is in office to keep Trump from being in office, why would anyone think that Trump could get voted into office this time around--especially now that Biden is already in office?
Basically, if the election was rigged, there's no reason to vote for Trump as this current election would be just as rigged. However, if the election wasn't rigged, there's reason not to vote for Trump as he's been clearly lying for the past several years. One way or another, it makes no sense to vote for Trump.
