The latest results from EPIC-MRA, a Lansing, Mich.-based company, show Schauer with a 45 percent to 43 percent lead over Snyder. Twelve percent remain undecided. The two-point lead for Schauer is within the poll's four-point margin of error.
EPIC-MRA last polled voters in July and found Snyder commanding 46 percent, to 43 percent for Schauer.
The latest poll numbers show a troubling trend for the first-term governor, who was elected in 2010 as a Republican wave swept over the country. Snyder has been slowly losing ground to Schauer throughout the summer as the Democrat makes a strong push on the airwaves.
Snyder has seen his lead disappear from a high point in May, when EPIC-MRA found the incumbent up by nine points over Schauer.
Both candidates will look to independent voters between now and November, as Snyder and Schauer have largely shored up their respective bases. Schauer now commands 83 percent support from Democrats and Snyder has 82 percent of Republicans.
