I'm so old I can remember when it was Village conventional wisdom that Democrats were too ruled by the all-powerful Left. Then in 2004 the Dems proved it by, for a moment, making it look like they were going to nominate a centrist governor from Vermont who committed the sin of opposing the stupidest fucking war ever. The point being, it was never true. More importantly, if it was the case that one politcal party was dominated by its base, one wonders why our sainted agendaless news media never bothered to actually give any kind of platform to those who apparently ran the party.
Now, of course, the Republicans are run by residents of crazy base land. Good that the media is finally starting to notice.
