the Democrats’ media base has served two functions. One, of course, has been to misinform the people who don’t pay much attention. It can still do that, though with reduced efficacy. But the other was to demoralize or intimidate the opposition. That part seems to have pretty much fallen by the wayside.
It started with Rush. Millions of people discovered that they were not alone. Then bloggers. Then the tea party. People have figured out that DC is the Democrats' company town. Waiting for a Republican inside the beltway to stand up against the news media onslaught and special interest money influence was a losing game. So they started without them.
