Iowa voters appear split on the 2020 Democratic presidential primary, according to a new poll that places four candidates within the margin of error for the top spot in the field.
Former Vice President Joe Biden and Sen. Bernie Sanders (I-Vt.) are leading the primary field in the first-in-the country caucus state with 22 percent support each, respectively, according to a CBS News/YouGov poll released Sunday.
South Bend, Ind. Mayor Pete Buttigieg closely trails at 21 percent and Sen. Elizabeth Warren’s (D-Mass.) 18 percent also falls within the 4.1 percent margin of error, placing the four candidates in a statistical dead heat for the top spot in Iowa.
Buttigieg saw a 15-point uptick since a CBS/YouGov poll of Iowa voters in September that placed him at 6 percent support.
Sanders’s support increased 3 points, while Warren had a 10-point dip since the September poll and Biden’s support decreased 3 points in Iowa since September.
Buttigieg saw a similar surge in a CNN poll released Saturday that placed him at him at 25 percent support, leading Sanders and Biden by 10 points and Warren by 9 points.
The new CBS/YouGov poll surveyed 856 registered Democratic voters and was conducted between Nov. 6 and 13.
