According to Robert D. Novak, it’s all “conservative supporters” of the B-Man, Barack Obama.

WASHINGTON, D.C.—What is an “Obamacon?” The phrase surfaced in January to describe British Conservatives entranced by Barack Obama. On March 13, the American Spectator broadened the term to cover all “conservative supporters” of the Democratic presidential candidate. Their ranks, though growing, feature few famous people. But looming on the horizon are two big potential Obamacons: Colin Powell and Chuck Hagel.

Personally, I think you can break it down to its component parts: Obama con.
Any questions?
