First of all, is Johnson the real deal? Has he been tested? Dunno.
If he turns out to be the real deal, then I want Trump to pick him as his VP almost ensuring his election as President in 2028.
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.
I appreciate what you’re saying but its better that he stay in place as Speaker to advance Trump’s agenda. Johnson appears far to intelligent and capable to waste away his talents in the largely ceremonial VP slot. JMHO
