Why do Black American's continue to vote for liberal Democrats who give them substandard representation and quality of government? Have conditions in inner city America really improved since the 1960's when this voting trend began? Government dependency, poverty and crime is all these people have gotten from Democrats. Free your mind and your ass will follow.
Well it's not like they're going to get better representation from the Republicans.
Also you seem to be making the assumption that representation only exists when people have income equality. It might just be that some of the places with the highest inequality means some people have massive amounts of money and everyone else is just well off, whereas further down the line you have the richest who are just rich, and the poor are really quite poor but income equality is closer.
Also you're assuming that only money makes your life better.
Lots of assumptions. Also, you've taken the top 100 members of Congress, what about the rest?
