> you should organize and advocate for both electoral reform and the minor party you most prefer during periods between elections

I totally agree with this.

>Once its clear who the major candidates are in the present election, you should still generally vote for the one least harmful to your interests

I don't agree with this, because the platform-creation calculus of the major parties is to ignore interest groups that will not abandon ship.

As H's platform makes clear, when there is sufficient loyalty, it's in the best interest of the candidate to edge as close as possible to the opposing party's platform, to attract as many swing voters as possible.
