Honestly, I don't see as he gains anything by constantly tweeting insults at people he doesn't like. When he's doing this, he's acting like a teenage girl who's spatting with some other little girl, over a boy that they both like.
I didn't vote for him to spend more time on Twitter than on getting the things done that he said he was going to do.
What he's doing by Tweeting as he does is put info out there on the same level as the Left. The emotion driven responses just distracts the Hell out of them while he goes about getting stuff done.
The two or three minutes a day Tweeting this stuff is actually quite valuable. #1, it resonates with his base, #2, it drives the emotion-driven Left bat scheit crazy, #3, it makes his enemies constantly underestimate him, #4, he actually lets out hints of what's really going on and what's about to happen.
Make no mistake, he is a very calculating individual who wouldn't waste time and energy on irrelevant stuff. As another poster mentioned, he's not working on his Final Four picks as the POS who last stunk up the Oval Office did.
