This isn’t the worst thing that can happen, but I would never bring Newt Gingrich into any political position like this. Old, faded political figures from the 1990s who have spent their careers as Beltway hacks belong in the Democratic campaign, not the Republican side.
He was my Congressman when he was first elected. He was throughout his career. In the past here I have been critical of Newt because of a few things I experienced as a constituent and how his Speakership and term ended.
That said, I’m just going to not worry about it right now, there are many other possible matches Trump could pick also. However I do have sympathy about your qualms about faded figures from the past. We are engaged in a battle now to keep the worst one from getting back into that White House.
