I agree with you about the spending - and growth of size and scope of government. Bad.
As a republican, I just can't rally behind McCain, though. He worked against the party with the whole "gang of 14" compromise that prevents qualified conservative judges from getting through to the bench.
What the next GOP candidate should promote is this:
1) Win the War 2) Close the borders 3) Confirm the Judges 4) Control the spending
(and promote the asbestos litigation reform bill :)
