Obama leads in the polls because the press would rather bring up Cindy McCains drug abuse then Barack Obama's. They would rather avoid the truth of his lack of character, credibility, and accomplishments then mention all of his mistakes.
I wonder if a white guy who did drugs as a young adult, went to church with racists and worked with terrorists. Had little to no accomplishments besides writing two books about himself. One of which was full of racist remarks that have since been edited out. Had not completed even one term as a Senator and had a record of voting present rather than taking a stand and thinks the same goventment that can not deliver mail should handle your health care. And should spread the wealth of people who earned money to those that have their hands out. I wonder if that guy would be so high in the polls as well?
I guess if no one bothered to report about their character flaws they would.
