Democrats erased painful memories from 2010, when they lost five congressional seats to Republicans. They landed almost all the big prizes on Tuesday’s Illinois ballot, taking back three of the seats they lost in the tea-party inspired surge two years ago, and picking up a fourth when Bill Foster defeated seven-term U.S. Rep. Judy Biggert. Among the three GOP freshmen unseated was U.S. Rep. Joe Walsh, the Obama-bashing tea party favorite, who lost to Iraq war veteran Tammy Duckworth in one of the most closely followed races in the country.
