Here's Jon Stewart's extended interview with Ornstein and Mann. I think this may be just the third cable interview they've had, after Chris Hayes and Eliot Spitzer.
But watch even Jon Stewart argue with Thomas Mann in the second part, insisting that Democrats' favored programs are secure and that the real problem is that both parties have what they want but they just can't exist together. (It's an extension of the Villager trope that Americans are selfish children who refuse to accept that they can't have it all.) He just can't hear what Mann and Ornstein are saying:
This all seems so obvious to me that it's downright banal, but I guess it's a real shock to the Village system. Good for the liberal outliers for having them on to talk about their thesis. But it's scary that this can't get a wider hearing.
