With barely 300,000 inhabitants (less than half a Congressional District), Michigan's Upper Peninsula never left much of a mark in Michigan politics. As a result, the State wouldn't look much different without it.
MI Presidential election results, 1960-2012:
As you can see, no Presidential winner has changed, and even the magnitude of their victory has remained almost identical. There really isn't much to see here. The PVI curves of old and new Michigan are also nearly identical.
In the last two decades, removing the UP has brought a benefit to Democrats of less than half a point (although funnily enough, this is enough to change the sign of MI's 1996-2000 trend, from R to D). In the past however, the UP was actually a bit more Democratic than the rest of the State (most notably in 1984 and 1988), meaning that this change would have weakened the Dem's position. Still, we're talking of really minimal changes.Capital:
Still Rick Snyder

Still Debbie Stabenow
(class 1) and Carl Levin
The Republicans' control over the State Legislature would also remain virtually unchanged, meaning that the gerrymander would still be there. Michigan would keep its 14 Congressional Districts as well, which means that CDs would be somewhat smaller in population. In terms of party split, it probably also stays the same at 9R-5D
