 Eight years ago, Senator Ted Cruz was booed off the stage at the Republican convention in Cleveland when he declined to endorse Trump. On Tuesday night, Cruz of Texas opened his remarks with the shouted declaration, God bless Donald J. Trump. Trump's VP choice, Senator J.D. Vance, who once called Trump America's Hitler and compared him to an opioid, is scheduled to speak today. The displays of unity stand in stark contrast to the dynamic facing Democrats, many of whom are increasingly uncertain that President Joe Biden is the right choice to take on Trump in November.
