1) From white people: Obama was the choice of the RNC because they could not beat Clinton or Edwards. They knew that liberals and progressives could be guilted into voting for a black man, but that real America is not "ready" for a black candidate.
2) From non-white people: White people set Obama up to win because the economy is going down the tubes. He will win the election and get blamed for all the bad stuff. After him, it will be impossible to get a non-white person nominated for a generation.
3) Hilary Clinton wanted to lose because she realized the economy would tank. This way she can run in 2012 after McCain beats Obama.
4) Obama was the choice of the DLC when it became clear Clinton could not beat Edwards. He is a tool of the Democratic leadership to keep out real progressives.
What's your favorite conspiracy theory? And who "allows" Obama to win anyway for these conspiracy theories to work?
