Someone should ask Perry, If executive experience is so important, then why is Obama no better a president in his second term than in his first?
Because he's not actually trying to learn or improve.
He's accepted that he's not going to get better at working with Congress -- he's not even going to try -- so he's just going to do what he wants to do whether it works or not.
He's trying a "brute force" approach (metaphorically speaking), rather than trying to finesse things.
