Active Vote Weight (AVW) is an estimate of what amount of vote weight would come from users active on the network if they all voted.
For a poll to be validated, it must get a certain % of AVW to have voted on that poll. For whitelist polls that's 40%, for others it's less. If a poll fails to reach the required number, its results don't matter and its as if it never happened. See the voting wiki page for more information.
I've created a bash script that uses the wallets RPC command to find the % of AVW for any Gridcoin poll made after 5.0.0 (i.e v2 polls).
I've put it on this GitHub Gist if you want to run it or look at it
Let me know if you are interested in a cross-platform Python version and if you run into any issues in the script
