Two-edged sword. Does dumb don know? Everytime he attacks President Obama it pleases his base. Guess what else it does?

Increase and STRENGTHEN Joe Biden's base.

Now does the dumb don continue to gamble on this just to give his base a quick thrill KNOWING he is also providing Joe Biden with more ammunition that strengthens Joe's coalition?

I know. Too complicated for dumb don to posit about. He "thinks" in brief seconds and gets bored so he stops and goes on to something else. A great deep serious thoughtful intelligent person dumb don is not. SIGH. If only!
