MADISON, Wis. (CBS 58) – Democratic presidential nominee Joe Biden holds a 45-41 lead among likely voters over President Donald Trump with less than a month to go until Election Day, a new Marquette University Law School Poll shows.

Biden’s lead over Trump has remained consistent since the summer. In June the poll had Biden up 50-44, in August Biden led 49-44, then in September his lead was at 47-43.

Other findings from the new poll include:

• A third of respondents think Trump has mild symptoms from COVID-19, while slightly more say they don’t yet know how ill he is.
• Most think that in-person campaign rallies should be halted, while a majority think the debates should continue.
• By a 2-to-1 margin, voters say Biden did a better job in the debate.
• More people than in September say they are very worried by the risk of getting ill from the coronavirus, and support for requiring masks in public places is slightly higher than in August when last asked.
• Over a third say they’ve stopped talking about politics with someone, and this varies by political party.
• The poll found 72 percent of respondents agree masks should be required in all public places

On masks, @MULawPoll reports 72% agree masks should be required in all public places. 26% disagree.
