activists is they have not really focused enough on making the case against president trump and they have really kind of emphasized for understandable reasons their differences among each other. if impeachment per se is the issue, but i do think there's a sense in the party that they would be better off spending at least more of this national air time and these big audiences trying to preview the general election case rather than just kind of the head of the stations that you sometimes get into on each other's climate plans for example. so you wrote a piece for the new republic arguing that joe biden's you know case for presidency is actually collapsing in your view. explain what you mean. >> well, joe biden's theory of change from the beginning of this campaign has been that once trump gets out and joe biden gets in, republicans are going step back and really work with democrats again to achieve some of the policy changes that have been talked about from health care to climate and so on. but i think it's hard for anybody who's watched the past couple of weeks and this impeachment situation of the president attacking joe biden
