I doubt any politicians are helping. It's not an issue. Not a real one, (In a politician's mind, that is) like Medicare, The Economy, or The War on Terror. There are only certain issues on which politicians will speak, and preferential treatment of the rich over the poor is not one of them.
The money for a costly campaign has to come from somewhere. (Always look to the money)
