WASHINGTON — For nearly nine months, Senate Republicans have watched their new president with a mix of aggravation and alarm. But it took Senator Bob Corker to take those concerns public and confront President Trump with his most serious challenge from within his own party. In unloading on Mr. Trump, Mr. Corker, a two-term senator from Tennessee, said in public what many of his Republican colleagues say in private — that the president is dangerously erratic and unstable, that he treats his high post like a television show and that he is reckless enough to stumble the country into a nuclear war. ***************** And we have the moron Trumptard conservatives to thank for this idiot being president. Idiots.
