Kirk's decision to give short answers and not go after Duckworth comes amid a campaign season in which he has had few scheduled public events or held events revealed to journalists only after the fact. Kirk suffered a major stroke in January 2012, barely a year into his Senate term, and has made his recovery part of his re-election story but has said he suffers no mental impairment. While Duckworth has provided a detailed binder of her recent health history, Kirk so far has provided only a single statement from his doctor.
