I was skeptical: once you accept that TDTers "naturally" make correlated decisions (in this type of problem), your vote "controls" something much more effective (the decision of a majority of voters). Then, even under generous assumptions about alternate uses of your voting effort, and aggregating this across all TDTers, and recognizing the mind-shields that various levels of drones put up, it's not clear why propagandizing is better.

That is approximately my thinking too.

To the extent that the drones are maximally mindless, your propaganda does nothing to change their minds, either on the object level (this election) or meta level (which political system is best). To the extent that the drones are "reasonable", a certain fraction of their votes will go toward the TDT-favored policies anyway, further reducing the threshold TDTers have to meet to get good policies.

I suppose this depends just how open minded the TDTers are when it comes to considering alternative ways to enforce their influence over policy in the case of pointless propaganda ;)
