Ok how many times has Mr. Amash endorsed his fathers opponent? In anything? In his entire lifetime?
Does Mr Amash have a big brother, GOP neocon Mitch McConnell?
I bet no matter how much evidence I could provide to you still you would be asking< How is (MR) purer?
I bet you actually think Rand Paul has the same Liberty, Freedom, views as his father, no matter what the evidence to the contrary.
So I suggest that you try to convince yourself with evidence before you ask this question.
But I knew you know and you were just fishing, hoping or somthing.
