Plus the mayor, city council and power holders of New Orleans have been basically Rats since the Civil War days.
What we are seeing is what happens to a blue city, blue county and blue state when something bad is happening.
The a$$holes in charge of the blue cities, counties and states are incapable of good leadership. All they can do is blame our president who didn't cause the problems they allowed to grow during their reign of power.
New Orleans is probably just the first such implosion of Blue Cities, Counties and their blue states in the coming decade.
