Well we are finding out now, aren’t we. McConnell, Pelosi and Biden are on their way out due to health problems due to age and accidents. Pelosi will probably be out of the picture in a year because of the broken hip. McConnell just fell and now has ‘leg stiffness” (an indication of possible blood clotting). And Biden, well, you know about Biden’s problems. Trump seems to be in rather good health for a dude his age, so the age problem may not take him. There comes a time when there is no holding on to power because you can no longer hold on to anything.
