  • Polling averages coming into Super Tuesday had Sanders winning Massachusetts with Warren in second, but the decisions by Pete Buttigieg and Sen. Amy Klobuchar to suspend their campaigns and endorse Biden significantly changed the dynamics of the race.
  • Warren had already disappointed in early-voting contests despite fundraising surges from her strong debate performances, making Super Tuesday all the more important.
