Question For John McCain

Question: If you're against gay adoption because children should be raised in an opposite-sex, two-parent household, how do you account for the greatest Olympic athlete of all time (Michael Phelps) being raised by a single mother and no father?

Oh, and the most important male in his life, his coach/mentor, is single, in his 40s, never married, no kids. Not that there's anything wrong with that. Unless you're John McCain.
