If McCain was in charge we would currently be in WWIII.
McCain wanted to back ISIS against Russia and Assad. McCain advocated attacking Russian forces in Syria which would certainly lead to war. This was before he knew he was terminal.
Now, McCain's thoughts and opinions are even more worthless than they already were. Now that he is terminal, he has no problem starting a World War. What does he care? He will not have to live through it.
McCain is pissed off at God. He is pissed off at Death. How dare they make him leave HIS office!? So now, I imagine that he plans to do as much damage as he can before he goes, to Trump and to all his conservative enemies that he hates. Unfortunately, that list includes most of us on this forum, the Tea Party, and anyone else he feels has disrespected him over the years.
McCain is going to be a destructive wild man over the next few months, right up to the last second that he is no longer able to hurt, destroy, and to do damage. He should be expelled from the Senate immediately for his own good, as well as for the good of the country.
