I guess LBJ was a saint, and the democrat controlled congress never had anything to do with the war.
I am not a Democrat and certainly not a liberal. But I will not defend Richard Nixon who was probably one of the worst Presidents in the 20th century. He imposed wage and price controls, he started a load of new domestic problems (remember who created the EPA and affirmative action). He was not loyal to you and your beliefs and there is no reason for you to be loyal to him.
