Can confirm - there are always some folks who slip by the nepo. My best friend became a WH Intern with no particular 'in' except for his past [hard] work with a state campaign.
Lol at anyone who thinks this is for the reason people think.
The real reason Craig's office did this is because there are a lot of political active, non college-educated DFL staffers. Many of them didn't go through college or just didn't to begin with. Many of these folks are non-white (particularly, Somali, where Minneapolis is one of the largest enclaves for Somali refugees in the US).
This is just to let the very active, motivated, driven, and hard-working politicos like them into Congress. This is good.
