Oh yea i forgot. The part about her doing all of it alone. I'm fairly sure she has employees. Some are paid others are not. She might have herself been an unpaid intern at some point (i don't care enough to look). Sometimes some jobs are outsourced and sometimes several politicians share services from outside companies. During campaign time all that explodes. Then there's the involvement of PACs where they buy services for her, but not directly. That type of stuff. I think that's in some degree every politician at her level and above (and some below but that's more inconsistent).
All that is between the options of doing it all on her own or having handlers.
