re: #280 lawhawk

Updated tier ranking of declared and potential to declare:

Tier One: Harris, Booker, Warren, Klobuchar, Gillibrand (no order ranking yet)
Tier Two: Beto, Brown, Garcetti, Inslee, , Castro,
Tier Three: McAuliffe, Delaney, Buttigieg
Tier Four: Bloomberg, Biden
Tier Five (don’t just go away.. go home): Schultz, Bernie, Tulsi.

I’m interested to see what kind of campaign Booker runs, should he get in.
