One week after Chicago Mayor Rahm Emanuel failed to clear the 50 percent threshold required to avoid an April runoff, new polls find a deadlocked race between Emanuel and progressive challenger Jesus "Chuy" Garcia.The Chicago firm Ogden & Fry conducted both polls. The first, a Wednesday survey of 1,058 likely voters, found Emanuel taking 42.7 percent of the vote to Garcia's 38.7 percent; the poll's margin of error was plus or minus 3.07 percentage points.
