In this Sept. 20, 2012, file photo, Republican candidate George Allen, right, and Democratic candidate Tim Kaine shake hands during a Senatorial debate for the Virginia U.S. Senate seat in McLean, Va. With Election Day just four weeks off, congressional candidates in both parties are avoiding answering questions that could alienate critical voter groups like women and seniors. Allen, for instance, won’t tell you how he feels about a law requiring Virginia women seeking abortions to have abdominal ultrasounds. (AP Photo/ Evan Vucci, File)
