Just two weeks ago we noted that President Bush had hit a new all-time low for the Washington Post/ABC News poll, which tends to be in the middle -- or slight right of middle -- of the major polls. Now, as Richard Morin reports for The Post, Bush has done it again by hitting another all-time low.

President Bush's public standing has hit record lows amid broad support for an independent investigation of the federal response to Hurricane Katrina and calls for postponing congressional action on $70 billion in proposed tax cuts to help pay for storm recovery, according to a new Washington Post-ABC News poll.

President Bush's overall job approval rating now stands at 42 percent, the lowest of his presidency and down three points since Hurricane Katrina savaged the Gulf Coast two weeks ago. Fifty-seven percent disapprove of Bush's performance, a double-digit increase since January.

Bush's handling of Iraq and terrorism also have never been lower, according to the poll. Thirty-eight percent approve of the way Bush is handling the situation in Iraq and half the county now approve of the way Bush is handling the campaign against terrorism.

A clear majority--54 percent -- now disapprove of the way Bush is handling the aftermath of Hurricane Katrina.

Importantly, much of the loss of support came from Republicans, whose approval of their President has fallen to 78 percent -- still a strong number, but not nearly as impressive as it had been throughout the first four and a half years of the Bush 43 presidency.

Bush is also losing his base on the question of whether there should be an independent investigation on the response to Hurricane Katrina, as there was following the attacks on New York, Washington and Pennsylvania. A majority -- 64 percent -- of Republicans agree with the 83 percent of Democrats who are calling for the creation of such a commission. Half of all Republicans and two thirds of all Democrats also oppose moving forward with the new round of tax cuts given the situation in the Gulf Coast.
