I don't know if you realized this, but in America, people actually elect the president into office. They, the voters, have the power.
It's these naive and gullible people who have been fooled into thinking that Obama will bring about these huge sweeping changes, and will right all the wrongs of the Bush administration. It's these same people who refuse to acknowledge or respond to the radical people Obama has associated with; it's these same people refuse see Obama's total lack of experience as a weakness; and it's these same people who, back in 2006, rallied to "take back" their country by electing a Democratic congress that has since done jack shit.
I'm probably going to vote Obama myself but not because I believe he's going to bring about any great political or economic change to this country, and it's a true sign of the times that people have become so desperate that they've deluded themselves into thinking that.
