What happens if Trump is assassinated?
Response: Bring in a ringer that looks just like him.
Tump is very good at what he does, but if we assume the Navy Intelligence is behind him then we have options.
What we need is for a Trump to win the election first. So if a body double is needed perhaps we can have one to lasts one day after he is inaugurated. Then the VP can be assisted by the Navy Intelligence to carry on Trump's initiative.
