I think there was a moment in the middle part of the century into the 60s, 70s when at least elite journalism claimed to be non-partisan. You can go back and look at it and wonder about how non-partisan it was.

For all the talk about the bitterness and the partisanship in American politics, is it really that bitter and partisan? Think of American history. Think of Joseph McCarthy. Think of the New Left. Think of [George] McGovern. Think of [Ronald] Reagan. Think of George Wallace. We've had an awful lot of real extremism on both wings.

It's been an unusual election [2016].

The repealing and replacing of Obamacare is very complicated. It is what a White House and congressional leadership, serious White House and serious congressional leadership, should meet on and work on and figure out a strategy of, and it may work and it may not. Obviously not every administration gets things through, even when they have much larger majorities in congress and a much larger popular vote than Donald Trump had.

Look, at actual Republican and conservative think-tank proposals to replace ObamaCare all have the pre-existing condition provision in, done somewhat differently from [Barack] President Obama's.

If you look at the polls - the conservatives are fine.I think there will be a fair amount of enthusiasm, or at least motivation. They very much want to remove President [Barack] Obama.

Mitt Romney has to convince the American public that they need to do something they're not usually inclined to do - replace a sitting president with a challenger. And unlike in 1980 and 1992, when the public was persuaded to do just that, the incumbent president has not been weakened by a primary opponent.
