The void in Congress left by Rep. Jesse Jackson Jr., who resigned last month after spending the second half of 2012 bouncing in and out of mental institutions and bars, is vast. And the bar is high for a candidate to meet the expectations of Chicago voters, who resoundingly re-elected Jackson less than four weeks ago even though he had disappeared without a word for five months and was under federal investigation for campaign finance violations. Luckily for Chicagoans, convicted sex offender and former congressman Mel Reynolds is bravely stepping into the breach.
