Jackson has been on medical leave since June, initially for “exhaustion.” He was treated at the Mayo Clinic for what was turned out to be bipolar depression, and left the clinic on Sept. 8. 

Since then, he has not campaigned or appeared in public. He released a robo-call over the last weekend asking for patience, which Davis and Rush echoed Monday night.

It may not matter. 

Despite concerns that the congressman’s absence and a host of legal issues could hurt his reelection chances, Jackson, first elected in 1995, has an overwhelming 58 percent advantage among all voters in a We Ask America poll released Monday, The Hill previously reported

Jackson is facing an unresolved House Ethics Committee investigation into his ties with former Illinois Gov. Rod Blagojevich and a separate federal investigation into his campaign finances. 

Jackson's closest competition in his Chicago district comes from Republican challenger Brian Woodworth, who is polling at 27 percent.
