Rahm Emanuel’s back in the race. The Illinois Supreme Court unanimously ruled Thursday that a lower court had erred in determining that Emanuel’s name be taken off the ballot for mayor, restoring his candidacy in the Feb. 22nd special election. “The novel standard adopted by the appellate court majority is without any foundation in Illinois law,’’ the court ruled. An appeals court had ruled on Tuesday that Emanuel did not meet the residency requirements to be mayor, since he’d moved to Washington D.C. to become President Obama’s chief of staff. Emanuel, whose name will appear at the top of the ballot, is leading in both polls and fundraising.
