Obama is absolutely right! He is the candidate and he is ready and willing to be scrutinized, even to the "lapel pin"!.. Michelle is to be respected and appreciated for not opposing her husband's presidential ambitions. I think that those who make Michelle a target for attack are the same people who see in Obama "an outsider" whose ideas for change should be feared. On the topic of change, I would not like to see Hillary offered the VP post. Someone so deeply compromised in the Washington establishment and power games is not be a credible agent to support change.
It's not surprising that a campaign that gets petty enough to scrutinize "lapel pins" (give me a break!) doesn't hesitate to use any low approaches they dream of. Apparently they never heard of "the higher road"!
