Trump was a net negative in the general election.
Check your math.
Trump is the only sitting President who has gained 17% support in his re-election that wasn’t elected in a 3 way race since FDR.
Clinton can’t claim that
Obama can’t claim that
Bush can’t claim that
Nixon can’t claim that
Hell even Reagan can’t claim that
But yes the only politician in nearly 100 years who gained 17% support after 4 years in the White House was a net negative (eye roll)
