Jackson Gaff a ploy?

I am wondering if the Jackson gaff about Obama was just a ploy to elevate Obama in the minds of voters. Think about it  the vast majority of Republicans hold Jackson in contempt and recognize him to be the Pariah he is. If he thinks poorly of Barak Obama, the good Senator can’t be all that bad, right?

Was the Jackson gaff simply part of the plan to pull Barak Obama to the center?
