If Obama wants any sort of a political/activist/public career after his presidency, he wouldn't pardon Hillary if she got indicted.
We have to go through the mental gymnastics of:
1) Those emails, sent by Huma on HER devices, are bad enough to indict HILLARY.
2) This investigation will be complete by the inauguration
3) Obama and Hillary are secretly f**king and Obama will throw away his integrity and career because you know, corruption/power/don't you know how politics work
