Candidates for the US Senate that need your support

I’m updating this as I read more, the goal is to write it all down in one place, compactly, with the best information I have in the time that I have.

Senate races that are plausibly close, to donate or volunteer.  Sooner is better,  do what you can.

This guy says “Iowa, Kansas, Georgia, Montana, Alaska, Texas”.  He’s using the “race is close, isn’t rolling in dough already” rule.

Your money goes farthest in these smaller states:
Maine: https://saragideon.com
Montana: https://stevebullock.com/
Alaska: https://dralgrossak.com
Iowa: https://greenfieldforiowa.com

A special election, seated perhaps in time for a Supreme Court vote:
Arizona: https://markkelly.com

These races are also competitive and states not too large:
N. Carolina: https://calfornc.com
S. Carolina: https://jaimeharrison.com
Kansas: https://bollierforkansas.com

Got to hold the seats we’ve got:
Alabama: https://dougjones.com 
Michigan: https://petersformichigan.com 

Don’t forget the state legislatures, those are also important if we want to get rid of Republican gerrymandering: https://idlewords.com/2020/09/effective_political_giving.htm
TLDR? These are good choices from that article, for flipping state legislatures and some overlap with up-ballot turnout.
