Well; he does things 'his way'; and gets paid well for doing just that. But really; what is the 'coo-coo' here? For challenging Obama? On his BC yet? Hope this is not the 'coo/coo' you are so referencing. Maybe his business MO; what??? (His hair?)
None of the things you mentioned make him coo-coo, imho.
Perhaps I used the wrong word.
Overly emotional might better sum The Donald up.
He loses his message when he gets his feelings hurt.
