Silent flip-flop. Amazingly, Slate is onto it

Compare the current “Seniors & Social Security” page with the previous version. Now, tell me why, oh why, would the Obama campaign decide to delete the following sentence: “[Obama] does not believe it is necessary or fair to hardworking seniors to raise the retirement age.” Is he trying to stoke anxiety about his position on Social Security?

I don’t know, but this changing platform surely looks like newspeak to me.
