So, who do you trust more...Comey, who served three Presidents of both parties, or the guy who said there were millions of illegal votes, that Obama bugged Trump Tower, that he saw "thousands and thousands" of Muslims cheering 9/11, who said Obama wasn't born in America, who tweeted that climate change is a hoax of the Chinese (then lied about posting that tweet during the third debate) and on, and on, and on.  If Trump told me water is wet, I'd start to doubt my senses.
I could not care less what his undergraduate degree was in.  It is irrelevant.
