The Brat Cantor race is a poor analogy. First, it’s a state versus a compact single district - but more importantly, Cantor was the face of amnesty in a lot of ways - and Cochran simply was not. Oh for two.
Some people here argue that poor people who vote dem don't want jobs. I don't agree. Even if that were true, people do want opportunity, and the invasion of the US takes away that.
