Never happen. People like Lott look forward to their retirement from politics as time to get on some corporate boards, consult or lobby, get paid for speaking. Because they have to maintain two homes, they spend every penny they make while in office. He has a very nice pension, but that won't make him rich.
If he has a temper tantrum and quits, costing the pubbies control of the Senate, all that will disapear. He will just be a despised middle class retiree.
He will hold on for the rest of his term, and help whatever Republican runs for his seat when he retires, because that is where the money is.
