B. the political rights of the english
I agree because a smart representor will base his oppinion off his state but its ultimetly up to him. Lets say 1/2 the country are idiots (not saying there are) but if so then they would most likely vote for the wrong person but you must qualify to be a representor to decide the fate of the presidency.
The answer you're looking for is D. The individual states.
Well, as far as I remember. I'm sorry if I am incorrect.
