You forgot to hit your sarcasm button for this one, didn't you?
The way I heard it, long ago, is that the Republican Party was so angry about FDR being elected to four terms that it was they who pushed through the amendment. And then they were kicking themselves when Eisenhower had to step down after two terms. (Don't know if that's true, and I'm too lazy to look it up. Chalk it up to anecdotal evidence.)The 22nd Amendment was a knee-jerk reaction to FDR being elected to four terms ... the concept of a four-term President scared the hell out of Congress and they pushed the Amendment through pretty damn quick.
Like you, I'm up in the air on term limits. It's a great idea when there's a dope in the office, not so good when there's a truly great man there. (Not that I think there are all that many great men, or women, in politics.) But I think it's something that needs to be fair. If Congress wants to impose term limits on the Presidency, then it's only right that there be term limits on Congress as well.
