WHO IS BROOKS TALKING TO?

I'd like to know by name the Democrats David Brooks has been talking to because I think he's full of shit with this claim:

Many Democrats, as always, are caught in their insular liberal information loop. They think the polls are bad simply because the economy is bad. They tell each other health care is unpopular because the people aren’t sophisticated enough to understand it.

As far as I can tell, we've been blaming the Noise Machine for spreading lies ("death panels") about the reform bills, NOT that the people aren't sophisticated enough.
