The Rev. Jesse Jackson will headline a rally in Tampa Tuesday to protest a new Florida election law Republicans say is intended to cut costs and prevent fraud, but that Democrats and civil rights organizations say is aimed at suppressing voter turnout to improve Republican 2012 election chances.

The goal is to rouse citizen opposition to convince the U.S. Department of Justice to overturn the law, said the Rev. Charles McKenzie, a local NAACP official and state coordinator for Jackson’s Rainbow PUSH Coalition.
