Ranked Choice voting allows a lot of strategic voting(log rolling) depending on how it is structured and multimember districts have some of the same defects. First, job is to devise a fair reapportionment system as opposed to the travesty of Prop 50. We need to press for simple solutions that will ultimately improve voter knowledge of their members. .
Citizens United has to go
This wretched decision has silenced the voices of all but the stupidly rich and greedy donors....

Reality is fundamentally complicated, and trying to think of it as simple is a shortcut that leads to bad results. People have to put in the work. There are no good shortcuts.
Multimember districts could fix the travesty of Prop 50 (depending on exact implementation). On average, three gerrymandered districts (rigged by Prop 50 to be represented by one Democrat each) would be rolled into a single multi-member mega-district with (on average) two Democrats and one Republican instead for the moment, but more likely to become one Democrat, one Republican, and one independent representative once RCV is implemented, which would get more independents to vote. Basically, multimember districts should reduce the effects of gerrymandering by putting enough members per district to give a more fair representation to the voters within.
It’s just the opposite: these measures eliminate strategic voting, which is already the norm. You know longer have to game out which candidate has a chance to ensure you don’t waste your vote: you just rank your choices!
Multimember districts ARE the reapportionment fix! In a district with 5 seats, any canditate needs just 17% of the vote, ensuring that minority points of view are represented. It breaks the two party duopoly in an instant!
