The Chicago Board of Elections said Tuesday the number of registered voters in the city is about 225,000 less than it was when voter registration closed four years ago.
Chicago Board of Elections Chairman Langdon Neal said it would be difficult to make up the deficit.
He said there doesn't seem to be the same level of enthusiasm in the city as it did when resident President Barack Obama was elected in 2008.
Neal calls it "a large hill to overcome."
The deadline to register for the November general election is Oct. 9.
