Thursday on the radio, LevinTV host Mark Levin said the Democratic party is a "cancer" on the body politic and that the "rot" caused by that party is greater than any foreign threat.

Levin began by citing a report about a Federation for American Immigration Reform study that calculated that half of all Americans live in "sanctuaries" protecting illegal immigrants. Listen:

"We have in this country leftist radical areas that have, for the purpose of immigration, seceded from the Union. They have nullified federal immigration law and they wrap themselves in humanitarianism," Levin said.

This lawlessness, aided by the courts and by Democrat politicians, enables the post-constitutional Democrat agenda to be enshrined, Levin argued.
