The first lady was asked, in an interview with ABC's Barbara Walters released late Wednesday, why she had ruled out launching a bid for office herself.
"I have learned from my husband, watching him, that it does require a great deal of patience to really feel the full impact of the work that you do on the ground," the first lady said. "It doesn't happen right away."
"She's honest and straightforward, which is not what you see in Washington much. She is exactly what we need around here," Clyburn said.
Earlier in December, a Public Policy Polling survey found in a hypothetical matchup between the first lady and Sen. Mark Kirk (R-Ill.) that Obama would win by double digits. The poll found Obama leading Kirk 51 to 40 percent in a head-to-head matchup.
