Put him in a very large tomb on which is inscribed every single tweet he ever tweeted.
Every word of every single rally speech he ever uttered
Every word of every TV appearance
I know. The tomb will have to be very huge but he is worth it.
That way the adoring worshippers can pilgrimmage there and read and reread and reread his every word.
IMMORTALITY
What perfecter way to honor his existence and what he did for this country than that?
