You may be aware of today’s special election for the U.S. House in Tennessee’s Seventh Congressional District. It’s getting plenty of attention because the race between a Democrat and a Republican is believed to be much closer in a district that usually goes big for the GOP.

Chris Cillizza’s preview of this election included a look back by Decision Desk HQ of previous congressional special elections, and it included a huge upset locally in 2008 that got a lot of attention at the time. That’s when Prentiss County Chancery Clerk Travis Childers, a Democrat, defeated Southaven Mayor Greg Davis, a Republican, for the U.S. House seat in North Mississippi. The seat in Mississippi’s First Congressional District came open when Representative Roger Wicker was selected to replace Senator Trent Lott, who had retired.

Even if the Democrat wins the special election in Tennessee, it still would not be as big of an upset as Childers defeating Davis 17 years ago to represent the region in Congress.
