You see, Barack *redacted* Obama has been misstating McCain's position on Social Security. Which isn't even central to McCain's campaign. But the lies seem to be central to Chicago politics - that is Obama's campaign.
Now, it is possible he doesn't really know what McCain and Bush have proposed.
And if he doesn't know the details of what McCain and Bush have supported, the question would be why not?Same old thing, more media bias.
Either way, it doesn't help his argument that he is the candidate of "change" he campaigns as. This is old-fashioned political fear mongering based on misstating and twisting the facts.
