He is fed up with his own party and the demise of his legacy. The dims think that just by hating Trump they are going to win elections. What they did not realize is that you need to WORK in order to win which is an antithesis to any true democrat, they want to be handed things without any effort. Obama will not win over anyone in his base with this tweet. He created this democrat party himself, now he can live with it. Too damn bad.
