MILWAUKEE – A new Marquette Law School poll finds former Vice President Joe Biden the choice of 48% of likely voters in Wisconsin, President Donald Trump supported by 43% and Libertarian Jo Jorgensen receiving 2%. Another 7% say they will vote for none of these candidates, don’t know how they will vote or declined to say. These results include those who are undecided but say they lean to a candidate. This is the final Marquette Law School poll before the November 3 election.
The results are little changed from the Marquette Law School poll conducted from Sept. 30 to Oct. 4, in which Biden was the choice of 47%, Trump the choice of 42% and Jorgensen the choice of 4%. Those results also included those who were undecided but leaned to a candidate.
Among Republicans, 7% say they are voting for Biden, while 86% are voting for Trump, 3% for Jorgensen and 4% undecided or declining to say. Among Democrats, 3% are voting for Trump and 92% are voting for Biden, with none for Jorgensen and 4% undecided or declining to say. Independents say they are voting for Biden over Trump by a 36-28% margin, with 12% for Jorgensen and 24% undecided or declining to say.
The poll was conducted Oct. 21-25, 2020. The sample included 806 registered voters in Wisconsin, who were interviewed by cell phone or landline, with a margin of error of +/- 4.3 percentage points. There are 749 likely voters, with a margin of error of +/- 4.4 percentage points.
Table 1 shows the trend in presidential preference among likely voters from September through October. None of the poll-to-poll changes in support is outside the margin of error.

| Poll Dates | NetDem-Rep | Joe Biden | Donald Trump | Jo Jorgensen | None/other (VOL) | Don’t know | Refused |
| 8/30-9/3/20 | 4 | 48 | 44 | 4 | 0 | 2 | 2 |

Sensitivity of results to turnout and undecided voters
The vote margins may be sensitive to assumptions about turnout. The model results for likely voters are based on those respondents who say they are certain they will vote or have already done so. Table 2 shows vote both if turnout is lower than the likely-voter sample implies and, by contrast, if turnout is higher using all registered voters as the sample. The results range from a margin for Biden of 3% in a lower turnout than expected, a margin for Biden of 4% in a high turnout in which all registered voters voted, and the previously mentioned 5% Biden margin in our standard likely-voter model.
Table 2: Vote by level of turnout
| Response | All registered | Likely-voter model | Lower-turnout model |
| Joe Biden | 47 | 48 | 48 |
| Donald Trump | 43 | 43 | 45 |
| Jo Jorgensen | 2 | 2 | 2 |
| None/other (VOL) | 1 | 1 | 0 |
| Don’t know | 1 | 0 | 0 |
| Refused | 6 | 6 | 5 |
In the likely-voter sample, 7% say they are undecided or declined to say how they would vote. To assess the probable impact of their votes, an “allocated” vote assigns these respondents to Biden if they have a favorable view of Biden and not a favorable view of Trump and assigns them to Trump if they are favorable to Trump and not favorable to Biden. If they are favorable to both or not favorable to both, they remain unallocated and remain undecided. Table 3 compares the vote among likely voters without allocation against the allocated vote. While the allocation reduced the undecided, refused and other categories, it does not change the margin, which remains 5 points in favor of Biden. The allocation does raise Biden to 50% and Trump to 45%, while Jorgensen remains at 2 percent.

| Response | Likely voters | Likely voters, including allocated vote |
| Joe Biden | 48 | 50 |

| None/other (VOL) | 1 | 0 |

Expectations for the election
Among likely voters, 91% say their minds are made up while 6% say they might change their minds. Among Biden supporters, 95% say their minds are made up. Among Trump supporters, 93% say their minds are made up.
Sixteen percent of likely voters expect Trump to win the election by a lot, 23 percent think Trump will win by a little, 29% think Biden will win by a little and 17% think Biden will win by a lot.
Eighty percent of Trump voters expect him to win and 11% expect Biden to win. Among Biden voters, 80% expect him to win and 6% expect Trump to win.
Twenty-seven percent of likely voters say they are very confident that the votes will be accurately cast and counted in the election, with 43% somewhat confident, 21% not too confident and 7% not at all confident.
Among Republicans, 61% say they are very or somewhat confident the votes will be accurately counted and 37% are not too confident or not at all confident.

In the poll, 41% of registered voters say they have already voted either by absentee or in-person early voting. According to the Wisconsin Elections Commission data, 37.5% of registered voters had voted as of the end of the poll’s field period on Oct. 25.
Among those who say they have already voted, 64% report they voted for Biden, 25% voted for Trump, and 2% voted for Jorgensen. An additional 9% declined to say for whom they voted. Among those likely voters who have not yet cast a ballot, 35% report they will vote for Biden, 56% for Trump and 3% for Jorgensen. An additional 6% said someone else or declined to say how they will vote.

Age group variation in this poll
In this poll, the 18-29-year-old sample is more Republican and more likely to vote for Trump than has typically been the case. This appears to be noisy sampling variation. The 18-29-year-old group is only 60 respondents (unweighted) which has a large margin of error of more than +/- 15 percentage points. Because vote by age has been an important topic, Tables 14 and 15 show the vote by age for this sample and compare it to vote by age for the last three polls combined, using likely voters. Given the consistency of Biden’s margin in multiple polls this year, it is likely that the 18-29-year-old result in October is a sampling anomaly rather than a real change. Because the group is small, this anomaly has little effect on the overall vote margin. If all age groups are weighted to match their long-term partisan composition, the overall vote margin changes by only 1 percentage point, to 48% Biden and 42% for Trump.

In late October, 22% say they are very worried about becoming ill from the coronavirus, a decrease from 27% in early October despite the rise of cases in the state. Nineteen percent say they are not at all worried, virtually the same as the 21% in early October.
Table 16 shows how worries have varied since March, when the percent very or somewhat worried was at the highest level seen so far, while the number of those not at all concerned has stabilized close to 20 percent for some time.

On Monday, Oct. 26, the Senate confirmed the nomination of Amy Coney Barrett to fill the vacancy on the U.S. Supreme Court created by the death of Justice Ruth Bader Ginsburg. Forty-eight percent say, if they were in the Senate, they would vote to confirm Barrett, while 38% would vote against her confirmation. This is a sharply partisan issue, as shown in Table 18.
