I like Bill Frezza’s idea:

"If elected I promise to vote "No" on any bill that proposes to expand government power for any purpose. I promise to vote "No" on any bill whose net effect does not reduce government spending. I promise to vote "No" on any bill whose net effect does not reduce federal taxes."

Frankly, if a candidate says that, all the rest falls into place.

Trouble is… Obama would claim that his bills meet this test. Politicians lie.
