Well, we've now reached a part where the defining question of elections is whether one party can eke out enough support among a single racial group - and increasingly, a single gender, a single religion and even a single age group - to win a national election. Its difficult to overstress this; the entire Republican electoral coalition is overwhelmingly white, increasingly male and increasingly above the age of 40. The Democratic coalition, by contrast, is Hispanic-American, African-American, Asian-American, Jewish, athiest, increasingly female... oh, and by the way, also contains a majority of Catholics and a higher % of white people than the Republican coalition has of any ethnic minority.
Twice now, the answer to whether that amazingly narrow coalition can triumph over a much broader one in a national election has basically been "No, and it can't even come that close"... but that very narrow coalition was enough to win a set of midterm elections when they were low turnout and ethnic minorities, young people and women did not turn up as much.
