If the Republicans were serious about cutting the deficit, they would immediately do away with these unneeded subsidies, and save the government billions of dollars. But they're not serious about cutting the deficit. They talk about that because it helps them get what they really want -- more money for their rich friends, and destruction of the social programs that help hurting Americans (programs they have never approved of). That's why every budget they have tried to pass in the last few years has cut help for ordinary Americans and included big giveaways to the richest people.
The Republicans truly are the party of the rich.
