It's a matter of who is irresponsible, and who is more irresponsible
The pushback on Katrina aid, which the White House is also confronting among House Republicans, represents the loudest and most widespread dissent Bush has faced from his own party since it took full control of Congress in 2002. As polls show the president's approval numbers falling, there is growing concern among lawmakers that GOP margins in Congress could shrink next year, and even rank-and-file Republicans are complaining that Bush is shirking the difficult budget decisions that must accompany the rebuilding bonanza.
Congressional Republicans are not arguing with Bush's pledge that the federal government will lead the Louisiana and Mississippi recovery. But they are insisting that the massive cost -- as much as $200 billion -- be paid for. Conservatives are calling for spending cuts to existing programs, a few GOP moderates are entertaining the possibility of a tax increase, and many in the middle want to freeze Bush tax cuts that have yet to take effect.
