Washingtonian magazine's ballots are in from over a thousand Congressional staffers... and the winner for Most Clueless Member of Congress goes... to... Wisconsin's Ron Johnson:

On the Senate side, Wisconsin’s Ron Johnson earned “clueless” honors the old-fashioned way, spouting gaffes on climate change (Greenland “was actually green at one point”) and hyperbolizing (Obamacare is the “greatest assault on our freedom in my lifetime”) often enough to inspire a website titled Our Dumb Senator. What likely put him over the top in the survey, however, was filing a nuisance lawsuit this year that would have deprived Hill staff of their health-coverage subsidy.
