That point was passed around 1934 during the Imperial Presidency of F.D.R.
It is unlikely to happen now.
I have wondered for sometime when the Black community was going to wake-up and realize that all of their entitlements were/are being sucked up by Hispanics. I currently believe that at some point in the not to distant future there will be inner city Black/Hispanic violent conflicts - not just drug and gang stuff but organized hit squads to take out the other side. We shall see, but the usual race pimps on the Black side have been very quite as of late - doesn't add up.
