He's pretty arrogant for someone who had to have his @$$ pulled out of the fire in his last primary.
This is his last term, if he even lives to fill it out. He blames conservatives for all of his troubles, particularly his near defeat in the last primary. He's looking into the abyss and his failures are starting back at him. He will be a bizarre footnote to history, cited only by the lunatic fringe and universally dismissed as the ultimate lightweight who happened to be involved in the most momentous events of his lifetime. History came knocking at his door, repeatedly, and he wasn't up to the task, repeatedly.
He's stuck between the first and second stages of Kubler-Ross' five stages of dying (thank you Bob Fosse and All That Jazz for educating me about that little bit of pop culture). He knows all of his failures, deep down, and he's lashing out.
Do not hate him. Pity him.
But don't stop working to marginalize him and undo the damage he does...
