*Chicago alderman candidate and rapper Rhymefest fought hard but lost with 45 percent of the votes to incumbent Willie Cochran’s 55.

But Rhymefest, born Che Smith, is not going down quite yet. Instead, he’s challenging the system and claiming there was  massive voter fraud.

According to the freshman politician, his opponent’s total was greatly inflated, however he has to prove it.

“We want to ensure that it’s fair and that every vote is counted, and that people who didn’t live in the ward of vacant lots weren’t people who were voting,” the former Kanye West -affiliate explained in an interview with ABC News. “We want to make sure that the 20th Ward voices are heard … We concede nothing.”

The other side says everything is legit and ‘Fest is just a sore loser.

He has yet to reveal his plan to prove his claim.
