[O]ur political system is set up in a way in which it’s very hard for an opposition party to be open to participating in any solutions to that because that would legitimize the party in power, which would keep them from getting there. And so they are engaged now in an ever more permanent campaign to obstruct, defeat, discredit, repeal anything that is done by – usually defined as – the president’s party….
But I think just as importantly, it’s [the Republican Party] become a party that believes it’s essential to stick to your principles and not engage in any kind of collaboration with – negotiating or compromise with – the enemy, which is defined as the other party. That’s unusual. And then you put that together with simply no respect for facts, for evidence, for science, and add to that the willingness to simply reject the legitimacy of the other side…. The peaceful transfer of power, the respect for the office of the presidency, the willingness to say, ‘We have our differences, it’s important to discuss those but in the end we’re all Americans,’ and so on, that’s rejected by a whole lot of Republicans right now.
