He has opposed and disappointed his paty ever since.
You really know nothing about politics in this region, but let me explain. A Republican will always win in GR. he did not come in on a Tea Party wave. Instead he lied about what he would do in office to DeVos's who supported his campaign financially and more importantly with their blessing.
He is an iconoclast and a Never Trumper, and frankly, he has supported the left on many critical issues. He was a thorn to his party long, long before trump, and no one in GR is at al surprised by this.
