1. Because he's black.
2. Because there are a lot of socialists, communists and Marxists around (really all different manifestations of the same ideology).
3. Because a lot of people really buy into the old saw that Republicans are for the rich and Democrats are for the little guy.
4. Because the Bell curve shows us that an IQ of about 100 is average, but that half the population falls under 100. So there really are a lot of people walking around with room-temperature IQ's.
5. Oh, did I mention that he's black? A Harvard educated black, to boot, who was handed a Nobel Prize?
6. And let's not forget that, to the media and other Dem shills, any Dem president is ALWAYS super smart. Because Obama's black from Harvard, he's a super giant intellect dontcha know.
7. Why...he's a history-making black man and we racist scum must never forget that.
8. Last, but never least, all the sexual perverts, pro-abortion "rights," and other "stay out of my bedroom" types just love the Dems. Throw in a slew of anti-military types. Quite a stew, that.
Obama starts with an in-built advantage: He has CA, NY, MA, WA, CT, DE, IL, in the bag even before the campaign begins.
His bedrock constituency are unionists; GLTB; Hollywood, Blacks, Single white females; high school-college grads (18-29); Jews, Muslims, Hindus, NARAL, NEA, La Raza, ACLU members, Journalists; and non-taxpayers. This crowd alone makes for 45% of the modern electorate.
