America has had 3 Irish presidents (Buchanan, Kennedy, and Reagan), 4 German/Dutch presidents (Roosevelt, Hoover, Roosevelt, and Eisenhower) and 36 English presidents (everyone else).
The vast majority of current politicians and movers and shakers belong to those three groups and the blacks. Wake me up in 100 years when someone from outside those groups actually has a chance.
It's going to take a lot less than that for Hispanics to become dominant in this country....
