The irony of McCain, of all people, using the term 'DOA' is rich.
The guy is taking some serious Meds. He is going to radiology daily, from what I hear. And his brain is not well. This is some serious stuff for him to still be running around in the Senate.
What we will see over the next months is that he will become increasingly more and more irrational, to the point where he is finally totally out of control. I'm not saying that as a gibe or an insult of any kind. It is a simple unavoidable fact of the reality of his situation.
At this point I wouldn't consider McCain to be a 'Republican' at all. Or a Democrat. I don't think even he knows what he is? He seems to be simply a mean, vindictive, dying old man, who is determined to screw up as much as he possibly can before he finally goes out.
Eventually, probably pretty soon, someone is going to have to take action on his behalf. There won't be a choice in the matter. I take no pleasure in saying this, but the plain fact is, he is going to go crazy relatively quickly. And I don't mean 'funny crazy' like Pelosi. This guy is going to lose his marbles completely. That's just nature doing what nature does.
