Has to be a RINO.
Actually he was very conservative. He won a special election to replace David Stockman when Stockman became President Reagan's budget director. He faced a tough primary challenge a few years later from Fred Upton. Just before the primary, Siljander released an audio tape asking people to "break the back of Satan" by defeating Upton. That backfired bigtime and he lost the primary.
He lists George H.W. Bush and Duncan Hunter as references #1 and #2 on his corporate website.
In the 80’s he was one of the most conservative congressman there was. Social and fiscal.
Innocent till proven guilty. But it looks like he’s in pretty hot water.
