With 12 candidates on stage, many of the lower-polling candidates hoping for a breakout moment took on Massachusetts Sen. Elizabeth Warren, who is largely considered a front-runner after her rise to about second in the primary polls nationally.

There were also a few heated moments between candidates on several issues. When it came to health care, South Bend, Indiana, Mayor Pete Buttigieg and Minnesota Sen. Amy Klobuchar accused Warren of not being straightforward about whether "Medicare for All" would raise taxes on the middle class.
