Michelle Obama is NOT pregnant, but…

Why are people interested in whether Michelle Obama is pregnant or not?  Maybe it’s just standard gossip… but I think there’s something more going on.   Michelle is almost exactly the same age as Sarah Palin.  If Michelle Obama found herself pregnant and test results showed that her baby would have Down syndrome… would she carry him to term, or would she choose to abort him?  Given her husband’s position(s) on the issue, how likely is it that she would make a very different choice than Sarah Palin did?  And would she share that choice publicly, or keep it hidden instead?
