Much congratulations to your Father. My grandfather was a lifetime Democrat, and Union Engineer, from Jump River Wisconsin. He voted Republican once, however, for Reagan. While I can't speak for him, I'm pretty sure he would have voted for your Dad.
Best Regards to the entire Trump family, Chase Perry
