Rauner didn’t go out of his way to associate himself with Trump; but trust me, Rauner was more than fine with the vast majority of Trump policies. He tried to keep a low profile on Trump, but he was hardly a moderate.
A lot of Trump's policies were red meat GOP policies. Of course there was overlap. Low taxes, small cap gains, less government regs, anti union. Yet all the die hard IL Trumpers thought Rauner was a RINO. I never thought Rauner hated NATO, loved Putin, or bought into this America First garbage that would let the Chinese take a huge mortgage out on Africa. If you can't see the difference, there is no helping you.
