Those numbers above represent Favorable/Unfavorable/Don't Know in the latest Rasmussen poll, and while Rasmussen itself notes that:
At the time President Obama nominated her for the Homeland Security post in early December, 43% had no opinion of her. Since that time, her favorable ratings have remained constant, but her negatives have increased. That’s fairly typical for politicians as they get better known.
...it's still not what you would call 'good' news - at least, if you're the sort of person who worries about whether people are still liking Secretary* Napolitano enough. For added amusement, check out this Hill article ("Napolitano splits the GOP") and try to figure out, precisely, how the GOP has been 'split' on the Napolitano controversy...
PS: President Obama tapping Napolitano for Homeland Security probably ensured that the GOP kept the Arizona Senate seat in 2010 - but I never really thought that it might wreck her career, too...
