Can Hillary tap dance until January? Yep, and she won’t even break a sweat.
She doesn't need to last until January. Anytime after November 6 -- presuming Obama is defeated -- she will be free to announce her resignation (effective in January, if she prefers) and dump the mess right back in Obama's lap.
There will no longer be any need to be a "team player" and protect The Won. After November 6, only one thing couunts: her own political viability.
