John Zogby has the first nation-wide polling following the President's address on Iraq. Surprisingly, the Bush did not pick up much support from his speech.

President Bush’s televised address to the nation produced no noticeable bounce in his approval numbers, with his job approval rating slipping a point from a week ago, to 43%, in the latest Zogby International poll. And, in a sign of continuing polarization, more than two-in-five voters (42%) say they would favor impeachment proceedings if it is found the President misled the nation about his reasons for going to war with Iraq.

In a more significant sign of the weakness of the President’s numbers, more “Red State” voters—that is, voters living in the states that cast their ballots for the Bush-Cheney ticket in 2004—now rate his job performance unfavorably, with 50% holding a negative impression of the President’s handling of his duties, and 48% holding a favorable view. The President also gets negative marks from one-in-four (25%) Republicans—as well as 86% of Democrats and 58% of independents. (Bush nets favorable marks from 75% of Republicans, 13% of Democrats and 40% of independents.)

Not quite the intended response, one might suppose.
