MILWAUKEE, Wisc. - Delegates to the Communist Party USA's 27th Convention here July 6-8 called for a stepped-up campaign for jobs, equality and peace and a fightback against the ultra-right agenda. The crowd, packed into a ballroom at the University of Wisconsin-Milwaukee, greeted the speakers with standing ovations, cheers and applause. The mood among the 520 delegates and guests seemed as fresh as the breeze that blew in from sparkling Lake Michigan.
