When Obama got the Democratic nomination, I was in a minority among people I knew, on two counts: 1) I didn't believe anything he said, and 2) I thought it was likely that he would become President.
Most people I talked to liked what Obama said, but they told me I was crazy if I thought America would elect a black man to the Presidency. I told them that it would be easy for a black person to win if he/she* gave people a reason to vote for them - and if they could motivate people who normally saw no reason to vote for either branch of the corporatocracy that rules America.
Election day came, and, by 7 p.m. Arizona time, Obama was a clear winner.
And, even though he's an amoral huckster, the meaning of his being elected is the opposite of what Bush's election meant.
In the long view, it doesn't matter that Obama is not what he pretended to be. America didn't vote for the reality of the man; it voted for the illusion. It voted for what he pretended to be - a man with a progressive vision, who would bring change. America, despite its infamous racism, wanted that change so badly that it was not daunted by the man's being black.
* I said "he/she" because the other myth is that America would never elect a woman President. Do you really think Oprah Winfrey wouldn't win if she ran?
