Joe Walsh labeled Tammy Duckworth a “failed bureaucrat” running a poll-tested campaign while the Democratic challenger argued the incumbent serves the tea party instead of his district.

Going head to head for two hours before a raucous audience of about 1,000 people in Rolling Meadows, the 8th Congressional District contenders debated on issues ranging from the future of Medicare to partisan gridlock.
