CHARLESTON, West Virginia — Republican voters rejected ex-convict Don Blankenship in a West Virginia Senate primary in which he sold himself as “Trumpier than Trump” but was vigorously opposed by the president. GOP voters in Indiana, meanwhile, chose wealthy businessman Mike Braun over two sitting congressmen to lead the party’s charge against a vulnerable Democratic senator in the fall. President Donald Trump and his allies cheered the West Virginia result Tuesday night, which helped avert a potential political disaster for a GOP already bracing for major losses in the November midterm elections. In both cases, Trump’s party appears to have avoided the missteps that doomed candidates in high-profile Senate races in the past.
