What's the opposite of "bounce"?

I suppose that would be "tank," as in "the president's approval has tanked to Nixon-during-Watergate levels." Can't imagine why.

A new Harris interactive poll has him at 26% approval, which is where Nixon was in Harris's polling in the summer of '74. Other findings:

• Dick Cheney also hit a new low with 21 percent of respondents giving him a positive job approval rating, down from 25 percent in April.
• Republicans in Congress are at 21 percent approval, also a new low in this category, which goes back to 1995.
• Democrats in Congress have 31 percent approval, higher than most of last year.
• Only 19 percent think the country is on the right track. Harris hasn't reported such a low number in 15 years.

Well, that's good news for Dick. Cheney, that is. Not the dead one. The NYT just reported that he had hit the almost unbelievable low of 13%. Almost unbelievable, but it is Dick.

The long national nightmare continues.
