NORWALK - The race for the 4th Congressional District is heating up in the final 10 days before Election Day. Local political experts say two-term Rep. Jim Himes (D) and challenger Steve Obsitnik (R) are close in the polls, with both candidates still canvassing for support. The National Republican Congressional Committee recently labeled Obsitnik a "candidate to watch." However, Himes says he feels confident about his re-election chances and insists his challenger's support may not be as widespread as it seems. 4th Congressional District candidates face offVIDEO: 4th Congressional District debate
