^ The terms are four years long, but there's no limit on the number of terms a president can serve.
I have to admit that I did that because I think the 22nd amendment is one of the most stupid-ass amendments Congress ever passed. It was an overreaction to one president who served four terms under unique circumstances. Prior to FDR, no president had ever served more than two terms because it's a goddamn impossible job that pretty much drains the life out of anyone who does it for eight years.
Having said that, there's no reason, none, to limit the number of terms a president can serve. Like I said, reality kept every president prior to the 22nd to two terms, and if another situation comes by where we have/need an FDR to serve four terms, I don't want that stupid-ass amendment to stop it from happening.
But that's just me.
I, on the other hand, find myself eternally grateful to the 80th Congress for putting into place a constitutional rule, and insurmountable barrier, that prevents George W. Bush from ever being elected to a third term as President of the United States ever again for the rest of time.
