Fox News has the president at a 33 percent approval rating, according to Brit Hume on Special Report.

Number one cause for disapproval? You guessed it, the war in Iraq.

Update: John McIntrye:

The President has got to get his Republican base back in the fold. If he can do that his approval ratings will stabilize in the high 30's and low 40's and he will be in a position to mount a comeback this fall. Bush could take sliding approval ratings into the high 30's in the RCP Average, but deterioration below 35% - it's not there yet, but the FOX poll could be a troubling leading indicator for the White House - starts to indicate loss of core support in his Republican base and that can become a very slippery slope which could effectively kill his presidency. He's got to pick a fight with the Democrats on something and get his base reenergized. Compromising with Ted Kennedy on immigration is not the answer to his political problems.

Build the wall on the Mexican border, Mr. President. If Ted Kennedy, Harry Reid et al get up and scream, all the better. Go to the mat in a head on fight with the Dems and light a fire under the base.
