It's not The Onion or an April Fool's, it's Rasmussen Reports:
It’s not exactly a vote of confidence in the powers that be: A sizable number of Americans think the undead would do a better job than the brain dead in Washington, D.C.
Thirty-seven percent (37%) of American Adults believe the federal government would do a better job than zombies running the country today. But the latest Rasmussen Reports national telephone survey finds that most Americans don’t share that view, with just as many (37%) who feel zombies would do a better job running the country and another 26% who can’t decide between the two. (To see survey question wording, click here.)
These findings are no surprise, given that 64% of Likely U.S. Voters now view the federal government unfavorably, with 34% who have a Very Unfavorable opinion of it.
I'm not sure about zombies, but I am prepared to believe that you could replace everybody who works for the White House and Congress with a random selection of folks taken off the street and not notice the change. I've never had less respect for the people who run Washington, regardless of party, which is saying something.
