Supporters for Sen. Bernie Sanders’ presidential bid who attended his Grant Park rally disagreed about whether they would vote for former Vice President Joe Biden if Sanders doesn’t win the nomination.

Over 15,000 people gathered to hear Sanders speak at the Petrillo Music Shell in Grant Park last Saturday. The rally took place 10 days before the March 17 Illinois Primary.

According to a Gravis Marketing poll conducted between March 10 and 12, 63% of likely voters surveyed supported Biden to Sanders’ 25%.
