I haven't been able to find any evidence that Clancy voted for Obama or Kerry, let alone that he was a Democrat or a leftist (which ought to mean more than just somebody who votes for a Democrat).
To be sure, any evidence online gets buried when somebody dies, but somebody who gave money to Duncan Hunter (for president, 2008) and Herman Cain and Alan Keyes (senate races, 2004) probably doesn't deserve to be attacked as a leftist, no matter how much he disliked a policy of a Republican president.
