On campaign reform (since it's such a litmus test for so many), he didn't sign it with fanfare, and expressed that it was a flawed bill. As a strict constructionist/constitutionalist, I could make the case that it's not the executive's place to decide whether a bill is constitutional or not; let the courts decide, which they will, and which Bush knew they would when he signed the bill. In the meantime, its signing has forced McCain to shut up and sit down -- not a bad thing in and of itself.
And is this not true of the Bush Apologists and Amnesty Deniers?
Their arguemnts are often rife with fallacious reasoning, deliberate ignorance of basic facts, personal attacks, and obsequious hero-worship.
