There is a push in that direction.
In her darkest hour last fall, Kathleen Sebelius suffered one of the deepest cuts from an old family friend who accused her of “gross incompetence” over the rollout of the Affordable Care Act and demanded that she resign as secretary of health and human services. Now she is weighing revenge.
Ms. Sebelius is considering entreaties from Democrats who want her to run against that old friend, Senator Pat Roberts, Republican of Kansas.
Several Democrats said this week that Ms. Sebelius had been mentioned with growing frequency as someone who could wage a serious challenge to Mr. Roberts, 77, who is running for a fourth term and is considered vulnerable. One person who spoke directly to Ms. Sebelius said that she was thinking about it, but added that it was too soon to say how seriously she was taking the idea.
