He should really take a look at 2022. Get elected to the Senate by taking away one of the D seats in Nevada, Arizona, Colorado, or Georgia, all of which had very slim victory margins for the incumbents. He could easily establish residency in any one of these states and then join the Senate club. Drive at least Romney and Murkowski absolutely nuts. Then run for President as a sitting Senator. Hell, twist enough arms and replace McConnell as leader.
Savannah is beautiful. Atlanta is no longer livable, I hear. Or he might try a beautiful hamlet called Statesboro, very quaint and Mayberry-ish, main street USA.
The Senate would simply refuse to seat him. Both parties would do this together. Guaranteed.
