State of the Union bounce

There is supposed to be a "bounce" in the polls after a State of the Union speech. It didn't happen this time, according to Newsweek:

The president’s approval ratings are at their lowest point in the poll’s history—30 percent—and more than half the country (58 percent) say they wish the Bush presidency were simply over, a sentiment that is almost unanimous among Democrats (86 percent), and is shared by a clear majority (59 percent) of independents and even one in five (21 percent) Republicans.
