Arianna on ABC's 20/20

John Stossel writes about his interview tonight with Arianna on ABC's 20/20, in which they spar over the presidential election and discuss HuffPost and her new book, Right is Wrong.

She was on the right, now she's on the left. These days, it seems as though Arianna Huffington is everywhere. For decades, Huffington has been a political gadfly and a perennial pundit on news shows. Now she's editor in chief of the popular news and opinion Web site The Huffington Post.

Huffington's politics lean left, but that wasn't the case in the mid-'90s when she was a friend to Newt Gingrich and a card-carrying member of the Republican Party. Now she's written a new book called "Right Is Wrong," in which she argues that the "lunatic fringe" of American conservatives have "hijacked" the country.

Below is a quick sneak peek from tonight's 20/20. Tune in to ABC tonight at 10 pm to watch. Also tonight: Arianna will be on Real Time with Bill Maher, 11 pm on HBO.
