Former presidential candidate Bernie Sanders gave a ringing endorsement to Hillary Clinton at the Democratic National Convention a day before she officially became the party’s presidential nominee. However, it appeared that some of Sanders’ supporters, those whom actress Sarah Silverman referred to as “Bernie or Bust,” have yet to be sold on Clinton. During the convention, many of them jeered any suggestion that they get behind the former Secretary of State. While it is likely that the biggest majority of those who supported Sanders in the primaries will cast their votes for Clinton this fall, it is highly questionable as to whether the holdouts may ever be brought into the fold. Sanders doesn’t seem to have much influence on these people in regard to where they’ll go from here. His appeals to them to support Clinton are apparently falling on deaf ears. While it is doubtful that any significant number of them will vote for Republican presidential nominee Donald Trump, they may split between staying home and voting for Green Party nominee Jill Stein. That could be enough to make the difference in certain key swing states (see Al Gore, Ralph Nader, Florida, 2000).
