Jim Geraghty of National Review and Greg Corombos of Radio America welcome President Trump's refusal to certify that Iran is honoring its part of the 2015 nuclear deal but wonder whether the deal will eventually be scrapped or be allowed to stick around.  They also approach the delicate issue of aging Republicans missing considerable time in the U.S. Senate and when the right time is to decide another term is not a good idea.  And they shake their heads as Chuck Todd of MSNBC rightly castigates the rise of activism cloaked as journalism but cannot see or admit that's what his employer does on a daily basis.
