Well, Mélenchon is far-left. Left is Parti Socialiste. Right is Les Républicains. Far-right is Front National. These are the French definitions of Left and Right, and probably have nothing to do with other countries'. Based on these definitions, the Democrats are Right and Republicans are Far-right. Whether they are good definitions, I can't say. But Mélenchon is definitely not plain Left, or Center.
