Cheney less unpopular than Bush

Bush is just incompetent, but Cheney is evil, yet...

According to NBC's Nightly News overnight polling on the Edwards announcement:

"According to the survey, 48 percent of the respondents disapprove of Bush's job as president, compared with 45 percent who approve. And while 44 percent approve of Cheney's performance versus 43 percent who disapprove, the poll also shows that 44 percent have an unfavorable opinion of him compared with 41 percent who have a favorable opinion."

48% disapprove of Bush but 43% disapprove of Cheney

I don't get it.
