President Bush's worst numbers came on the issue of Social Security. He clocked in at 31% approval and 64% disapproval.

(I'd actually be curious to hear from pollsters out there what the lowest ratings for a president has ever been on any significant issue. I mean, how much lower than thirty percent does it go? With the possible exception of Nixon at the very end of Watergate, how often has a president been under, say, 25% on any issue of significance?)
