Davis has also received donations from the campaign committees of other incumbent Republican members of the U.S. House - including $1,000 from the campaighn of Rep. Ann Wagner, R-Ballwiin - who face little or no opposition in their campaigns.

Callis, a former Illinois circuit court judge, had her best fund-raising quarter of the campaign, taking in just more than $400,000 from July through September. Her campaign report filed Wednesday showed she spent just under $600,000 in the third quarter, and had about $546,000 in her campaign coffers on Oct. 1. Through that date, she had raised $1.77 million over the entire campaign.

Both Illinois races have also been buffeted by heavy advertising spending from other groups, including the Democratic Congressional Campaign Committee and the National Republican Congressional Committee.

The new FEC reports come a week after the Democratic Congressional Campaign Committee (DCCC) announced it was pulling roughly $420,000 in advertising on behalf of Callis on St. Louis television and directing it to other Democrat congressional campaigns around the country. But the DCCc still planned to advertise on Callis's behalf on Champaign, Ill., TV for at least three weeks in October.
