A week or so ago a reader from Arkansas wrote in to offer his theory of how Mike Huckabee has gotten so far. He pointed out that Bill Clinton and Mike Huckabee had always had cordial relations. He surmised that Clinton was grateful that Huckabee had not piled on during the impeachment hearings, or the various Whitewater-related investigations, even though, as his successor in the Governor’s mansion, Huckabee might well have known things the national and conservative media wanted to learn.

We all say that the Clintons would do anything to win, the writer noted. Who, he asked, is financing Huckabee? Where did Huckabee get the seed money to start the race, and to fly around, once he had begun to take off? Who would benefit most if Huckabee became the nominee?

The reader was convinced that none other than Bill and Hill were Huckabee’s ultimate backers. Given how divisive Huckabee is, how well they know know the passions of the Evangelical community (and deep anger there, if my inbox is any guide), and the magnitude of money in Bill’s “library fund,” well, it’s as plausible an answer as any to “how the hell did this happen?” Huckabee is the candidate easiest for any Democrat to knock off, by a long shot. And there goes the GOP coaltion for a long time to come. Now that would be quite a Clinton legacy.

A week ago I found the letter writer merely entertaining. But who knows?
