Rep. Tom Tancredo's (R-Colo.) second TV ad of the presidential campaign focuses on Central American gangs like MS-13.

The ad shows images of dead bodies lying in the streets of Honduras while a narrator says "mothers killed, children executed -- the tactics of vicious Central American gangs now on U.S. soil."

The narrator says Central American gangs are wreaking havoc in America "thanks to gutless politicians who refuse to defend our borders." Tancredo, according to the narrator, is the one man who dares to speak out for border security.
