going. tantrum as governance. and even the president's close friend, he's better than this. dan, you called it governing by cattle prod. what is happening? it feels like we're in another level of republican concern about the president. >> well, you know, i think you could argue it's another level. i think it's a continuing level. i think this comes and goes. there are moments when something happens and i think you have to give senator corker the responsibility for ratcheting it up this week for what happened a week ago today in the tweets. what we've seen from the president both on the health care and on the iran agreement, we've seen this effort of him clearly frustrated in action. clearly wanting to send a signal to his base that he is trying to do the things he said he would do. but without a clear solution or a path to get to where he wants to get to. so he throw its to the congress. and says you all fix it.
