Kathleen Sebelius should be fired now. In fact, she should have been fired many months ago. She is in charge of a major healthcare overhaul that to date has been nothing short of a complete disaster. The website to enroll does not work, and she has provided no solutions for Obamacare's myriad problems.
Ultimately, the buck does stop with President Barack Obama. However, any problems with the healthcare website should be answered by the Health and Human Services secretary. If anything, Sebellius should resign because of the handling of healthcare.gov. Firing cabinet members is rare, but Obama won't do that because he's going to stick to his guns.
