Should Justice Kagan recuse herself from hearing the Obamacare case?

According to 28 USC 455, a Supreme Court justice must recuse from “any proceeding in which his impartiality might reasonably be questioned.” The law also says a justice must recuse anytime he has “expressed an opinion concerning the merits of the particular case in controversy” while he “served in governmental employment.”

Does this statue say anything about spouses of justices, thereby implying Justice Thomas recuse himself? How long will this argument go on?

If Herman Cain cannot handle the pressure of running in a Presidential primary, before it really gets nasty, what happens if he is Commander-in-Chief of our military?

Finally, I am going back to school.
