George Will explains in his latest Newsweek column why Democrats should approach the November elections with trepidation:

How many dead legislators walking might there be in December? Political analyst Charles Cook notes that in July 1994, four months before the Republican House landslide, Congress?s job approval was 53 percent. In October 2006, percent of Americans approved of the job Congress was doing?and a month later Republicans lost control of both chambers. In recent polls, approval of Congress has ranged from 19 to 26 percent.

Americans usually exempt their particular representative from their normal disparagement of Congress. Today, however, with 62 percent saying the country is on the wrong track, the Wall Street Journal/NBC poll shows 57 percent want to elect a new representative, the highest total in 18 years. Peter Hart, a Democrat who helps conduct this poll, says voters ?are just looking for change.? Change they can believe in?
