Boston, MA — March 10, 2019 — A new Emerson College poll finds unannounced candidate Joe Biden leading a Democratic field of 13 candidates with 40% of the vote in Michigan, followed by Bernie Sanders at 23%, Kamala Harris is at 12% and Elizabeth Warren at 11% round out the only four candidates in double figures (registered voters, March 7-10, mm, n=317, +/- 5.5%).

With Biden not officially in the race, the Emerson poll asked Biden voters who their second choice would be; Sanders would be the most popular alternative with 42%, followed by Harris at 23%, and Warren at 18%. Sanders received 50% of the vote in the 2016 Michigan Democratic Primary.

Age remains the dividing factor in the Democratic primary race, as Sanders leads among 18-29 year olds 32%-27% over Biden, but, as consistent with recent Emerson polls in New Hampshire, Iowa, and South Carolina, Sanders’ support drops with older voters as Biden captures over 44% of voters over 30 in the Michigan Democratic primary.

In a potential Republican Primary, President Trump leads former Gov. Bill Weld 89% to 11%, similar to what other Emerson polls this winter have showed in Iowa, South Carolina and New Hampshire. (registered voters, March 7-10, mm, n=306, +/- 5.6%).

Statewide, President Trump has a 52% disapproval and 40% approval (registered voters, March 7-10, mm, n=743, +/- 3.5%). More concerning for the President is that 56% of Michigan voters said they are unlikely to vote for Trump (of which 52% are very unlikely to vote for him); 44% of voters say they are likely to vote for Trump (37% are very likely). The President’s image appears to be declining since the 2016 election, as 50% of voters said their opinion of the President has worsened since taking office, while 33% said it has improved.

Likelihood of Voting for Trump in 2020, Michigan, March 7-10

Voters are split on whether the President has kept his campaign promises as 52% responded that he has not kept his campaign promises and 48% he has kept his campaign promises.

Likewise, voters are generally split on how the President is handling key campaign issues including abortion, immigration, healthcare and foreign and economic policy.(n=673, +/- 3.7%)

  • Abortion: 50% approve/50% disapprove
  • Immigration: 46% approve/54% disapprove
  • Healthcare: 43% approve/57% disapprove
  • Foreign Policy: 46% approve/54% disapprove
  • Economic Policy: 49% approve/50% disapprove

A potential bright spot for the President is that 62% of Trump voters in 2016 voted in support of Trump compared with 38% who voted for Trump in opposition to Hillary Clinton. Spencer Kimball, Director of the Emerson Poll, thinks that “once a Democrat is nominated, Trump might be able to boost his own appeal by lowering his opponents through attacks”.

In potential 2020 General Election match-ups, Trump trails the top Democratic candidates, but all are within the poll’s margin of error, except for against Biden where he trails by 8 points. However, significant gender, education and age gaps are emerging as Trump leads with men but trails with women, and Trump leads with less educated voters while Democrats lead with younger voters. Kimball finds that “a larger divide on issues based on age may be playing out in both the primary and general elections. Sanders appears to be the champion of the youth vote in the Democratic primary, while in the general election, older voters are breaking for Trump.”

The Michigan statewide Emerson College poll was conducted March 7-10, 2019 under the Supervision of Assistant Professor Spencer Kimball. The sample consisted of registered voters, n=743, with a Credibility Interval (CI) similar to a poll’s margin of error (MOE) of +/- 3.5 percentage points. The data was weighted based on 2016 voter model, age, ethnicity, gender and region. It is important to remember that subsets based on gender, age, party breakdown, ethnicity and region carry with them higher margins of error, as the sample size is reduced. Data was collected using both an Interactive Voice Response (IVR) system of landlines only (n=520) and an online panel provided by Amazon Turk (n=223). Visit our website at ​
