Have you noticed that McSame is only talking about Obama lately and now Hillary and Biden.
Are McCain voting for Obama? No...
Then why McCain has nothing to say about himself and his ideas and policies?
Answer, because they are just the same ideas and policies of George Bush's that have sunk the country in crisis domestically and internationally. So McBush wants to keep the negative smoke screen to avoid scrutiny.
The golden rule of credibility, when you spent more time talking about your opponent than yourself, there is something wrong with you.
