"GOP presidential hopeful Herman Cain came down hard on immigration
Saturday on the campaign trail, telling crowds in Tennessee that part of
his policy would be to build an electrified fence on the Mexican border
that could potentially kill anyone trying to enter the country
illegally. He backed away from that proposal Sunday morning, however, saying he wasn't serious about the idea."
