Is Joe Biden mentally competent, Joe tells a lot of stories about himself that are obvious lies easy to prove, yet I think Joe actually believes them . These are claims he made that are all false and extremely easy to prove as being false. So why he would lie about it is beyond me. Of course he might think that hid voters are stupid enough to buy his story's as the truth. He claimed he came from a coal mining family , that he was arrested in south Africa and arrested in Civil rights march, that his wife was killed by a drunk driver , that his present wife almost died in House fire. That he graduated in the top of his class with a full scholar ship and had 3 degrees . He said he was a professor and taught classes. There are more many more . Again all very easy to prove as Bull.
