It just makes sense.
The former CNN giant will guide next Tuesday's debate in Chicago, which will be broadcast on the Internet. The candidates taking part are the Libertarian Party's Gary Johnson, the Green Party's Jill Stein, the Constitution Party's Virgil Goode and the Justice Party's Rocky Anderson.
Johnson's Libertarians are on 48 state ballots, screwed out of Michigan because of the "sore loser" law (Johnson ran for the Republican nomination before switching, remember?), and denied Oklahoma because the state didn't let Johnson keep the vacant Americans Elect ballot line. Stein's Greens are on 37 ballots, including most of the swing states, but not including New Hampshire. That's key, because it makes the GOP-friendly Johnson the only local spoiler. And Goode remains just popular enough in south-central Virginia to queer things for Republicans.
Here, normally, I'd place some punditry about Rocky Anderson, but I honestly think that the average person who accidentally clicks on this blog while looking for "Dear Prudence" has more electoral oomph than he does.
