When Howard Schultz is inserted into hypothetical matchups as a third party candidate, the Democratic candidate’s share of the vote drops. Biden receives 54% of the vote when it’s just him against Trump, but his share of vote share drops to 51% when Shultz presents himself as an option. Trump’s vote share drops only by 1%. The same applies to Sanders: he receives 52% of the vote against Trump in a head-to-head matchup, but it drops to 48% when Schultz is included.
However, in the state of Wisconsin at large, Trump’s disapproval is at 49%, with his approval at 41%. 45% of voters said they were likely to vote for Trump in the general election, with 55% indicating they were unlikely to vote for the President.
