Could you write your comment better than this? It's pretty obvious you are baiting someone into asking "why?". But your comment by itself adds nothing to the conversation.
I just read up on Mark Warner, he doesn't look that bad. At the very least he seems to stand with Ukraine and against fascist dictators, which is weirdly enough a minority in Congress nowadays.
This is a very rich man, he is not being forced to do anything. What he does is what he believes and you don't need to spend time coming up with a complex explanation past that. He needs no one's charity.
