Point 4, Be cautious and intentional about mission creep, makes me think of environmental- and animal-focused political parties such as the Greens and Animal Justice Party in Australia, and the Dutch Party for the Animals in the Netherlands. The first formed as as an environmental party, and the latter two formed as animal protection parties.
All three of these have experienced a lot of mission creep since then (Animal Justice Party to a lesser extent than the other two). The prevailing wisdom from many is that this is a good thing. A serious political party should have a position on every issue, some will say. But the sense I get from your post is that this may not be the case, because just like with a movement, a political party can become partisan by taking a position on every issue and adopting a political leaning of some kind.
