No it doesn't.       Presidential authority has nothing to do with race in the modern US constitution.

One way to get clarity on the boundaries of law with such action is to take it to court.    

Did you hear President Obama insult the competence or suggest bias on the part of the Judge in this case?     

Ask the President if time spent in court isn't part of the 'game' when you play hardball.    He's quite familiar with the process.

I've know some Hank Williams types and they can be 'anti' about anything when they get to drinkin.  The can also be great fathers, hard workers, honest, brave, trustworthy.......    I know many are biased about black culture, most would never do anything to a black person without extreme provocation.    Most know 'a black guy that was cool'. so while shallow, not even these guys go by skin color alone.   Now if you make a move at their sister in the bar, all bets are off about that nice guy stuff.
