Andrew Gelman on the election:
Election 2008: what really happened: ...Here are the take-home points:
1. The election was pretty close.
2. As with previous Republican candidates, McCain did better among the rich than the poor. But the pattern has changed among the highest-income categories.
3. The gap between young and old has increased–a lot. But there was no massive turnout among young voters.
4. Obama gained the most among ethnic minorities.
5. The red/blue map was not redrawn; it was more of a national partisan swing.
6. The pre-election polls did well, both for the national vote and for the states.
