U.S. Rep. Judy Biggert's campaign has released the results for an internal poll conducted earlier this week. According to the campaign, the 13th district incumbent has a strong lead of 61 percent to 28 percent over Democratic challenger Scott Harper. The polling was done by Republican pollsters Linda DiVall and Randall Gutermuth.

Earlier this week, Harper released the results from his own internal poll that showed waning support for Biggert.
