For the fourth straight poll, GOP Gov. Scott Walker and Democratic challenger Mary Burke are locked in a neck-and-neck race.
The latest Marquette University Law School poll, released Wednesday, shows the two candidates tied at 46 percent each among registered voters in Wisconsin.
Last month, Walker held a three-point lead over Burke among registered voters.
Among likely voters, Walker received a slight bump from August to September, holding a 49-46 percent lead over Burke. Burke led by two points among likely voters last month.
With all numbers within the margin of error, there is no clear frontrunner in the race for governor.
In the race for attorney general, Democratic candidate Susan Happ's sizable August lead has evened out to an effective dead heat among registered voters. Happ now leads Republican Brad Schimel by one point among registered voters, while Schimel is up one point among likely voters.
