I tend to doubt this will happen. Hussein’s ego is just too big to let his “woman” get into the limelight like that. Michelle has been fairly low profile and has stuck to fairly non-political tasks, unlike Hillary.
I read a couple of months ago that there was talk of having Michelle as the next Dem candidate for President since Obama won’t be able to run again (unless he simply does anyway!) and he has effectively prevented any new material from developing in the Dem party.
This is all part of a plan, and this is the “testing the waters” moment. I’m sure if she runs, she’ll win, and then she’ll be lined up to be the next Dem presidential candidate.
