It is up to the INDIVIDUAL to decide if the job offered is better than the job currently held.
Obama
Biden
Sebelius
Emmanuel
Hillary Clinton
They ALL quit one job to take another.
They ALL Promised their original constituents that they would fill out their full term of office, at some time during their campaigns, did they not?
So, you say, in effect, that the duty is to those who voted for the office holder?
What the hell difference does it make, then, for the new job to be “better” or “worse” than the old job?
You have painted yourself into a corner, by your own hand.
Case dismissed!
So what’s her new job?
