THE ULTIMATE DARK-HORSE CANDIDATE: James Taranto: Nobody is challenging Obama in the primaries–and doing surprisingly well. “We now have seen Obama held under 60% by a slate of three candidates–antiabortion extremist Randall Terry, federal prison inmate Keith Judd and Tennessee lawyer John Wolfe–not to mention Nobody. . . . And while lefty pols and pundits may take some comfort in attacking these Democratic voters as ‘racist,’ that doesn’t seem a promising way of persuading them to vote for Obama–or to return to the party in future elections.”
