From many responses, I'll go with Occam's Razor -- under what possible set of circumstances are 45% of the US electorate not going to vote Stupid Party each and every time? MSNBCCNNCBSABCNBC could be off the air tomorrow and Stupid Party would still pull 45%. Unenlightened self-interest, aka the rabble votin' funds for themselves out of the treasury, is not a media problem...
Studies show hardcore libs and conserves each make up about 25%-30% of the population, that leaves 40%-50% of swing voters...the people who actually decide elections.
