I do not understand what geographically or demographically she adds!
my reading is that kamala check the "minimum" box (female), and has a bonus of being POC. that's good enough, and let's face it, biden is the candidate of good enough. so while others might be even better than kamala, she is sufficient. if biden has a personal preference for her (they work well together/have chemistry, has the policy chops he's looking for, etc.) then that might tip it. i'm not saying i agree with this, just a plausible explanation...
Abrams (a person whose resume is so wax paper thin I’m stunned she gets mentioned, but I digress...)
as many rookie/inexperienced politicians have proven time and time again, the lack of a resume is a good thing. nothing to attack. certainly helped the orange buffoon defeat the trainwreck in 2016.
