Republicans take it on faith that the deficit can be balanced solely by spending cuts. When asked to specify these cuts they NEVER can. They take it on faith that government can be cut because they have no actual knowledge of what the governmnet does. When forced to specify they say food stamps, foreign aid, PBS and Planned Parenthood. All these programs together don't add up to 100 billion dollars. But Republicans have no use for logic. They don't want to pay taxes. So they have to say spending cuts alone can balance the budget. This belief makes as much sense as believing in the tooth fairy.
They can't because the backlash for saying you'll cut social security and medicare would be too intense. They can't cut defense because that pays for their campaigns. They have very little left to cut, this two party system which elects people based on how much money they can raise is a joke.
