You saw two moderate Republicans who stayed away from social issues win, and one conservative Republican who campaigned on the social issues lose a Congressional seat that had been in Republican hands since Grant was president (literally).
In Virginia, you had the added issues that the Dem was not a strong candidate, was not from the part of the state where Dems need to do well to win, and engendered voter resentment when he tried to make too big of an issue of the social issues using very old evidence. In NJ, you had the added issue that the incumbent Dem was personally unpopular and a former Goldman Sachs CEO at a time when everyone hates Wall St. In both those states, the overwhelming majority said that Obama had nothing to do with their votes.
In NY #23, by contrast, the right wing made that campaign their own, and they lost. Translation: if the Republicans continue to let their right wing dictate decisions, they will continue to lose.
Electorally yours,
