She's gonna win 53-47, not by 15
What is so hard to believe about a double digit win? Both Granholm and Snyder did it in 2006 and 2010, respectively. Snyder probably would have done it again in 2014 if he didn't get so unpopular. And if you respond with "Trump won this state," consider that Snyder's blowout win in 2010 came 2 years after Obama won MI by almost 17 points.
Edit:Granholm's 14 point win in 2006 actually looks similar to Whitmer, polling-wise:
