>> david khchalian, thank you s much. joining us now, david gergen. alice stewart, who also is a republican strategy, and symone sanders, who was bernie sanders's press secretary in 2016. thank you all for being here. david, the headline this morning on axios called it a tsunami. this was a wave. was it a tsunami? >> i think it comes about as close as you get to a tsunami in politics. yes, it was a wave and it overwhelm eed everything else. and it has changed the story line already. i think it sends a clear message, a thunderous message, if you like, to the republicans. they need a serious course correction in washington. that means the president's behavior, a lot of things he says, the crazy things he says and that sort of thing. but they also need to revisit health care and get deeper into the numbers that david chalian was pointing out. it was an important issue, but which way does it cut? do people want to keep obamacare or not? but i would tell you the democrats shouldn't be too
