Incumbent Rep. John Kline (R-MN02) has seen his lead over Democratic challenger Coleen Rowley dwindle to just 8%, according to a SurveyUSA poll.

The poll shows Kline with a 50%-42% lead over Rowley, a former FBI agent.

While Kline still leads reasonably comfortably, the poll shows a significant shift over the past month.  A September poll had shown Kline leading by 20%, 55%-35%. 

The poll was conducted October 13-15, and has a margin of error of 4.4%.
