Among Republicans, Trump’s approval rating has held remarkably steady. The week Mueller was named, according to Gallup, Trump’s GOP support stood at 84 percent. In the days after Donald Trump Jr. was revealed to have written, “I love it” in response to a Russian offer of dirt on Hillary Clinton, it reached 87 percent. In Gallup’s last poll, taken in late November, it was 81 percent. Trump’s approval rating among Republicans has not dipped below 79 percent since he took office. None of the revelations from Mueller’s investigation—nor any of the other outrageous things Trump has done—has significantly undermined his support among the GOP rank and file…

Could Mueller or some enterprising journalist uncover revelations so epic that they shake Trump’s hold on the GOP, and give Republican senators cover to support his removal? It’s unlikely. After all, the vast majority of Alabama Republicans still support Roy Moore. Most conservatives consume pro-Trump media, which will downplay or distort virtually anything Mueller or the mainstream press discovers. And the more aggressively Democrats push for Trump’s removal, the easier it will be for Breitbart and Sean Hannity to rally Republicans against a “left-wing coup.”
