I knew there was a link but don't remember ever seeing video of Obama himself admitting the link. This seems to have been swept under the carpet, and having this accessible to as many people as possible is only doing the MSM's job for it. This link to a terrorist (who apparently also funded Obama's education) is far graver than anything that has come out against any of the other three P/VP candidates.
Be careful not to fall into the political junkie's trap of assuming the general public reads as much political discourse as you or I do.
