He is president of the entire country, not just his constituency.
How is ANY President supposed to represent the entire country when the country has a large group of people that call themselves Republicans and those people HATE the President and want absolutely nothing to do with anything he does?
Kinda hard to represent the entire country when part of the country feels like you all do.
I want Obama to say fuck off to the Repuibs and do what I want him to do. He has been representing me just fine.
