Rep. Jesse Jackson Jr. (D., Ill.) tells National Review Online that Rahm Emanuel’s residency status “will be a challenge” to the White House chief of staff as he mounts a mayoral run in Chicago. The race, Jackson predicts, “will be a thoughtful contest amongst very capable and able people.”

Still, he warns that “there are people who have lived in Chicago for more than a year who are gathering signatures, [people] who are likely to meet the ballot qualifications.”

The Wall Street Journal has a good wrap on the race here.
