republicans in congress have increasingly made the choice to lock arms, circle the wagons around them, view themselves as a defense effort than as any kind of oversight or restraint and the more president trump violates those norms, the more energy flows into those who are unnerved by the possibility of him operating without constraint. if you look at the special elections since 2017, without doubt, the most powerful force has been the intensity among the voters who believe that trump is outside of the norms and congress needs to be offering more of a restraint and a check line. if he goes down this road it may or may not cause him more trouble in 2020. you can guarantee it will cause more turbulence for republicans in 2018. >> we've got a lot more to discuss because remember that glowing health letter claiming that then candidate trump would be, quote, the healthiest individual ever elected to the presidency.
