Considering how difficult it was to get anyone remotely MAGA in the Speaker’s chair, I think it’s best to leave him where he is. Anyone Trump picks is guaranteed to become VP if Trump wins, so there is no difficulty filling that position at all.
The difficulty is continuing the MAGA effort 2028 and beyond after Trump is gone.
That is why Trump’s VP MUST be someone committed to restoring America’s Free Constitutional Republic by DISMANTLING the $3+ trillion unconstitutional portion of the federal government, our greatest enemy, which is now totalitarian.
