Read the sections on taxes and government. It can be inferred. Besides welfare reform what other specific proposals have been made in the past that cut gov't spending? Without 60 votes in the Senate, nothing is going to happen. So why shoot yourself in the foot for Election Day? Entitlement reform is where the bulk of that spending is. Look what happened to the President's attempt at Social Security.
Didn't happen when Republicans (Conservatives?) held power, so why should I believe that not mentioning cutting spending is an election ploy?
In 1994, the Balanced Budget Amendment was something Republicans campaigned for.
