Thanks to TSA airport pat-downs and the continuing debate over illegal immigration, Homeland Security Secretary Janet Napolitano remains one of the better-known – and most unpopular – members of President Obama’s Cabinet.

A new Rasmussen Reports national telephone survey finds that only 25% of Likely Voters have at least a somewhat favorable impression of Napolitano, down from 32% in June of last year. Forty-seven percent (47%) have an unfavorable opinion of the former Arizona governor, while 29% are not sure what they think of her. The new findings include seven percent (7%) with a Very Favorable view of Napolitano and 29% with a Very Unfavorable one.
