She just might be the most fiscally conservative candidate running. She is certainly more conservative than the current POTUS and his former Republican dominated rubber stamp Congress. Would McCain be likely to bring down the deficit? I don't know, and don't think anyone else does either at this point. We do know that he was a part of said rubber stamp congress.
Real fiscal conservatives in Washington have gone the way of the ivory billed woodpecker, and if they're not brought back from the brink of extinction pretty soon, it won't just be the pols calling for change. We're all liable to be asking for change on the street corners.
