That is far from certain.Some presidents may not want to have the same legacy as Ford(lost re election,unpopular with low approval ratings, entire presidential legacy is pardoning a crook)
You've reported little realty so far. You've only put forth highly speculative reports and have then plagiarized their musings as your own.
It IS 100 percent certain. Short of murder ( and even then perhaps there would be a pardon), the successor would clear the slate and the country would move on. This is the way the world works.
It is not 100% certain.When Ford did it he didn't know what the consequences would be.When it happens again a president will ask himself if he wants the same presidency and legacy of Ford,many wont.
What's the reality there? That Flynn resigned and that Comey wrote memos? Thank you for reporting that.
So what happens is not reality and what's reported is not reality, no wonder your narrative revolves around ignoring reality.
Trump has a strong base that will not go away easily. Here is a question for you. Which voters elected Ford as President? Answer: None. Nor was he ever elected Vice President by voters. So there are any number of reasons why he went poof as soon as the voters had a choice.
