Do the Republicans have more or less radical groups within than the Democrats?

Honestly, there are more radicals associated with the Democratic party. Now liberals will claim that groups like the Tea Party or the NRA are radical groups but non have initiated in or advocated violence. Meanwhile groups like ELF, ALF and ARM are animal and enviromental right radical groups that are considered terrorist groups by the FBI. The Obama campaign website had a link for the New Black Panther Party and Fred Phelps, pastor of the Westboro baptist Church, is a self proclaimed Democrat.
