RINO's who are not conservatives and will not vote that way. If there were 55 conservative votes in the Senate, you'd have a point. There aren't.
Weak leader who compromises and never uses a veto?
So let me get this straight. Bush should have been a "strong leader", by refusing to compromise on the $1.5T. And he should have vetoed the $1.3M because it wasn't $1.5M. By the Senate passing a $1.3T tax cut, the Dems and RINO's can legitimately claim they passed a large tax cut bill. Then they point to Bush's veto as depriving the American people of that tax cut.
So not only do we not get a tax cut, but we've strengthened those who fought for the smallest cut possible. Wonderful.
