There's also a long list of Congressman who were basically Some Dudes who lucked into running against an incumbent that suffered a major scandal during the campaign.
Chris Smith, Michael P. Flanagan, Joseph Cao, Tim Mahoney, ect.
There's also a handful of the 2006/2010 freshman class that were longshots swept in by a wave. Chip Cravaak, Nancy Boyda, Dave Loebsack. My favorite is Carol Shea-Porter, who Howard Dean couldn't even remember the name of on Election night.
Yeah Cao beating Jefferson and Flanagan beating Rostenkowski in very Dem Districts.
