In the campaign for Philly D.A., the gloves are officially off. And the increasingly hostile and overblown rhetoric emanating from the camp of the increasingly desperate incumbent, Larry Krasner, may ultimately come with a price tag. Carlos Vega, running for the Democratic nomination in the May 18th primary, yesterday filed notice of a libel and slander suit against D.A. Krasner's campaign committee, the Real Justice PAC of San Francisco PAC that is Krasner's biggest campaign contributor, and Shaun King, the PAC's co-founder.
