[Donald ] Trump is more important than all of us. He's more important than the media.

People used to complain in the 50s and 60s and even in the 70s when I was in school, studying political science, that "if only we could have two political parties that presented a choice, but there were all these liberal Republicans and there were all these southern Democrats who are conservative so people just don't have a clear choice."

The most devastating indictment of the president's proposal is that it threatens to destroy virtually everything about American health care that's worth preserving. Under the plan's layers of regulation and oversight, even seeing a doctor whenever you like will be no easy matter: access to physicians will be carefully regulated by gatekeepers; referrals to specialists will be strongly discouraged; second opinions will be almost unheard of; and the availability of new drugs will be limited.

Republicans can also point to an alternate path. They can draw upon genuine experts to explain what should be done.

Maybe one thing that has happened is that the claims of non-partisanship of the mainstream media have been a little bit exploded. Mostly I'd say what, if anything has caused the change, are just the obvious technological changes - proliferation of easier access to getting your opinions out and the proliferation of media.

Actually, not because of anyone's intention but just because of some sociological and some other things that have happened over 25, 30 years, the parties have sorted themselves out much more ideologically, which has some benefits and some costs.

There's a sort of romanticizing of the past. When you actually think about the past, you know it's a little different.
