George Bush gets no respect from his fellow Republicans. The House GOP voted to extinguish his Points of Light Foundation and narrow his Clean Air Act. Curbing the Americans with Disabilities Act to ease burdens on business is next. In the Senate, Phil Gramm raps Bush with lines like, "I don't want to be the `Education President,"' and "Don't read my lips. Read my record." Bush's top defender? Bill Clinton, who lauds him for quitting the National Rifle Assn.
