A new CBS News poll in Iowa finds Joe Biden, Bernie Sanders and Pete Buttigieg tied in the Democratic presidential race with 23% each.
They are followed by Elizabeth Warren at 16% and Amy Klobuchar at 7%.
Key takeaway: Sanders leads the field on two key measures: 43% have definitely made up their minds, and 67% feel enthusiastic in a state where enthusiasm can be an important motivator for voters to go out and caucus.
