Joe Biden’s edge on Donald Trump was largely unchanged among likely Wisconsin voters in the latest Marquette University Law School Poll.
Forty-six percent of likely voters backed Biden, while 41 percent favored Trump. Libertarian Jo Jorgensen was at 4 percent, while 8 percent said they were undecided or planned to vote for someone else.
Biden had a 4-point edge in the last poll at 47-43.
The survey went into the field the day after the first presidential debate, while about half of the interviews were conducted after the president announced he was positive for COVID-19.
Poll Director Charles Franklin noted a series of events in recent months have failed to swing the race either way. Biden’s edge has been between 4 and 6 points since early May.
“This is just a function of people being very, very dug in on their choices,” Franklin said.
The phone survey was in the field Sept. 30-Oct. 4. The sample of 805 registered voters included 700 likely voters. The margin of error for registered voters was plus or minus 4.2 percentage points and plus or minus 4.6 points for likely voters.
The sample was 45 percent Dem and 44 percent Republican. The long-term split is 45-45.
