Todd Akin, Claire McCaskill trade more punches in Senate race

Todd Akin's campaign on Wednesday demanded that Sen. Claire McCaskill release her and husband Joe Shepard's tax returns for the years since her election in 2006. The demand came the same day McCaskill began airing three new ads directly criticizing Akin's stand on emergency birth control for victims of rape and incest.
