Political Circus: Will the real Mayor Emanuel please stand up?

Washington (CNN) -- Politics is serious business -- but not all the time.

A big f------ deal

The Atlantic.com has a Twitter exclusive:

"It was the best fake Twitter account ever, deftly satirizing Rahm Emanuel, and elevating the Tweet and the f-word to the level of literature. But the mystery writer was never revealed - until now."

That man: Dan Sinker, founder of the Punk Planet 'zine, journalism professor and avid Chicago political watcher.

Some @MayorEmanuel gems, slightly edited because it's not very family-friendly:

"Turns out crowdsurfing your way up to a stage takes a long f------ time. OK, victory speech--let's f------ do this"

"Driving around in Axelrod's Civic, doing loops around the block outside Chico's offices, my a-- hanging out of the missing window, laughing"

Geography 101

It appears that Texas Gov. Rick Perry is in need of a geography refresher course.

On Monday, the Republican governor told reporters that "Juarez is reported to be the most dangerous city in America," Politico reports.

The only problem? Juarez is a city in Mexico, across the border from El Paso.

So how did they do?

Badly -- with the exception of five-time "Jeopardy!" champ Rep. Rush Holt, D-New Jersey.

He "bested the machine," the Wall Street Journal notes.

No "Dancing" for Christine

ABC revealed the lineup for the upcoming season of "Dancing with the Stars," and one name was absent from the list: ex-Delaware Senate candidate Christine O'Donnell.

The Republican recently announced on her Facebook page that producers for the show asked her to be a contestant.

Maybe next time.
