Democratic first-term Sen. Gary Peters is leading Republican challenger John James, but the margin is tight.
The poll, which was done by EPIC-MRA of Lansing for the Free Press and its outstate partners, shows Peters up 45% to 39% for James, with 5% supporting a third party candidate and 11% undecided. That compares to a 45%-41% edge for Peters a month ago.
With a margin of error of plus or minus 4 percentage points, Peters' 6-percentage-point advantage suggests he holds at least a narrow lead over James, though he is lagging Democratic presidential nominee Joe Biden's level of support in the race against President Donald Trump in the state.
The Peters/James matchup is one Republicans still have hopes to flip. The campaigns are expected to spend $100 million combined before it's over. It is still very much up for grabs, polling suggests:
"He (Peters) is doing less well in southeastern Michigan (than Biden) and running a few points behind in most of the other areas, but he still has many of the same patterns (levels of voter support) as Biden," said EPIC-MRA pollster Bernie Porn.
