Hillary is taking herself out. The arrogance and failure to really understand the electorate she and Bill display had them thinking they could do anything they wanted, break any laws, violate national security procedures and the gullibility of the Democratic voters would still give them the White House again.
Nonetheless, it wouldn't surprise me if Michelle, and ultra-left wing socialist, would think she could run and win. She hasn't got the "charisma" of her husband, and despite his so-called "magic campaign touch" which is more accurately credited to election fraud and ballot-box stuffing, she won't be able to transfer it over to herself.
