Q. Isn’t this just Emanuel’s opponents exploiting Illinois’ strict election laws to try to “deny voters choices” as Emanuel’s supporters have argued.

A. Yes. It’s a storied tradition. In 2004, Emanuel used a ballot challenge to try to oust his primary opponent for Congress . President Obama won his first election the same way, using ballot challenges to knock all his opponents for state Senate off the ballot and win by default.
