You saw the meltdowns? It was pretty bad. Like refusal to accept results, disbelief, shock, horror...these guys are so stupid. They trusted in some insane gut feeling rather than look at the polls. Every poll had Obama up, across the board. These are the people who are supposed to inform the populace and they live in such an artificial bubble.
As for the numbers, which I love to look at, it gets obvious you can't win without some minority vote. You need 50 points to win, here is the break down by voting.
Total Minority= 28%. Will be 30 to 31 next time.
-Blacks = 13% points and increasing slowly.
-Latinos = 10% points and increasing fast, they are actually 15% of the population.
-Others = 5% mostly asians, pacific islanders, natives, mixed etc...
Total White = 72% and decreasing about .5% a year.
Also men vote less than women (45/55) and older people vote more than younger (hard to quantify, the youth vote can be highly variable election to election)
Obama got like 24/28 points possible with minorities. That means he can get only 26/72 whites and win. He ended up with around 28 for the win.
