DURANGO, Colo. -- The Ku Klux Klan says membership is booming in Colorado because of the growth of the radical right.

Imperial Grand Wizard Cole Thornton says the United Northern and Southern Knights of the KKK is active and successful recruiting in Colorado, but no membership numbers were available.

Southern Poverty Law Center spokesman Mark Potuck tells the Durango Herald (http://bit.ly/AneXPp) the radical right in the U.S. has grown enormously in the last 10 years, particularly since President Barack Obama's election in 2008.

According to the Southern Poverty Law Center, a nonprofit civil rights organization, 12 white supremacist groups are currently active in Colorado.
