It’s only hypothetical this point, but a survey done by Public Policy Polling gives Mrs. Obama the lead over Sen. Mark Kirk 51 to 40 percent, should she choose to challenge Kirk in 2016 for an Illinois senate seat. From PPP.

“If Michelle Obama decided she wanted to follow the Hillary Clinton route once her husband leaves office in 2016 and go to the Senate, she’d have the upper hand on Mark Kirk. She leads him 51/40 in a hypothetical head to head. Kirk’s approval numbers are ok with 34% of voters approving of him to 19% who disapprove. But those numbers are no match for the first lady, who’s seen positively by 60% of voters to 33% with a negative one.”
