In his instantly famous Tuesday Senate floor speech — one his hometown newspaper called a “bombshell” — Sen. Jeff Flake (R-Ariz.) decried the “destructiveness” of President Trump’s politics while warning of the perils of succumbing to electoral considerations; of politicians’ “fear of the consequences” of speaking out; and of bending to “the rules of what is politically safe.” Flake, who has voted with the president more than 90 percent of the time, wondered aloud what he, and we, would tell the next generation when they ask, “Why didn’t you do something?” He rallied Americans not to let Trump’s habitual offenses become the new normal, never to “meekly accept the daily sundering of our country.”
