Huffington Post is calling it "RAHMAGEDDON" on their front page:

An Illinois court on Monday threw Rahm Emanuel's name off the Chicago mayoral ballot, possibly ending the former White House chief of staff's bid to lead his hometown.

By a 2-to-1 vote, an appellate panel overturned two previous decisions and ruled that Emanuel is not eligible to run because he moved to Washington D.C. for two years.

There are obviously appeals on the way.
