Democratic U.S. Rep. Sean Casten opened up a lead Tuesday as he tried to hold off Republican challenger Keith Pekau, the mayor of Orland Park, to win a third term in a Chicago-area contest that has drawn lots of high-profile national attention and money as it has tightened up in recent weeks.
Progressive state Rep. Delia Ramirez won handily over Justin Burau in the new Latino-leaning 3rd District that meanders from Chicago deep into DuPage County.
