damn, this data is hard to find
so people earning less < 30k vote Obama 62-35 (the biggest margin of any income demographic, what a surprise)
they make up 20% of the voters
20% of 27% = 5.4%
Obama won 51 - 47

5.4 - 4 = 1.4% for Romney
the numbers don't lie, and that's just using people with family income < 30K
PS: I'm not saying these people shouldn't be allowed to vote, I'm just pointing out Vettard is wrong about the results
If someone can find a detailed income demographic by state, I'd be happy to recalculate the electoral college or at least for the key swing states
most breakdowns are
< 50k
50 to 100
100+
