Political candidates have long accused their opponents of assorted faults and misdeeds. Occasionally, those charges have even had some basis in fact.
But Timothy Ray Murray, the lopsided last-place loser in the June 24 Republican primary in Oklahoma's 6th Congressional District, has gone beyond the usual fare of calling his rival a liar, cheat, phony, extremist, socialist and/or corporate stooge.
Instead, Mr. Murray contends that Rep. Frank Lucas, the five-term incumbent who won the primary with nearly 83 percent of the vote, is actually dead - and that he man who celebrated as the purported victor is an imposter.
From Mr. Murray's campaign website: "It is widely known Rep. Frank D. Lucas is no longer alive and has been displayed by a look alike."
Mr. Murray, who asserts that Rep. Lucas was killed during a trip to Ukraine in early 2011, has also pledged to "never use a look alike" to represent the 6th District.
Fortunately, though, that promise won't be tested anytime soon: Mr. Murray drew a mere 5 percent of the primary vote.
As for Rep. Lucas, his office said that not only is he still alive and well at age 54, but that he has never been to Ukraine.
Rep. Lucas also told KFOR-TV in Oklahoma City: "It does come as kind of a shock to read that you're not you."
And that would be a political identity crisis far more profound than flip-flopping on a controversial issue or even changing parties.
