Here is another
graf that addresses in full context the point you're concerned with:
The former community organizer from Chicago and the former Baptist preacher from Arkansas have little in common in terms of political views. But as I wrote here a month ago, the author of “The Audacity of Hope” and the new man from Hope, Ark., are flip sides of the same coin. The slogan “change” — a brand now so broad and debased that both Hillary Clinton and Mitt Romney appropriated it for their own campaigns — does not do justice to the fresh starts that Mr. Obama and Mr. Huckabee represent.
Rich isn't comparing Obama and Huckabee in the sense you alluded to... what I think he means is that with the emergence of Obama on one side and Huckabee on the other, the Establishment in both parties has hit the wall. What is emerging is two candidates who arose from very humble beginnings, and, with the voters, have repudiated the Big Monied Establishment across the entire spectrum, both Left and Right.
This, IMHO, is the Big Picture stunning reality for the Corporate Barons/War Machine makers/Big Oil/Big Media types. Suddenly, the future of their whole bloated, greed-driven, blood-hungry agenda is evaporating before their very stricken eyes.
There is a monstrous tsunami on the horizon, and these people are helpless to escape it.
And they know it.
