In 2018, Rasmussen Reports predicted that Republicans would win the generic ballot by 1 percentage point while the actual election results had Democrats winning by nearly 9 percentage points. This error of nearly 10 percentage points was the largest polling error out of major firms who polled the national generic ballot. Rasmussen pushed back against critics after their miss, claiming that "the midterm result was relatively poor for Democrats compared to other midterms" despite the Democrats having scored a historic margin in the popular vote.
