M&M Party refers to the Republican Party and the two groups that support it. Millionaires and Morons! The Republicans only care about the richest 10% of the population and act accordingly. If you are not super rich and vote Republican you are in the moron faction of the M & M Party!
The big corporate execs are Millionaires and vote for the M&M party for the tax benefits, while Joe the Plumber represents the moron faction of the M&M party!
