Then the winning platform in that district would be the one where you're mostly aligned with the party currently occupying that seat but differ on the pirate issues.
So you'd end up with a blue pirate party and a red pirate party based on which district they're running in. They would work with each other on pirate issues, but they'd generally caucus with different major parties on a per-district basis.
It might also help to prioritize getting range voting or STAR voting so this would stop being necessary.
Also even if this party does not have success, just by running they can change the other candidates policies
Only implemented recently iirc.
I quite like the German model:
> Every elector has two votes: a constituency vote (first vote) and a party list vote (second vote). Based solely on the first votes, 299 members are elected in single-member constituencies by first-past-the-post voting. The second votes are used to produce a proportional number of seats for parties, first in the states, and then on the federal level.
(from wikipedia)
In CZ, we can prefer individual candidates from the party list. Plenty of VIPs lost their putatively safe seats because they were disliked enough.
This is only a result of first past the post voting. If a third party had any significant support, they would split the vote with the major party most like them and hand the election to the major party least like them. Then the third party merges with the major party most like them and we're back to two parties.
Switch to STAR/range/approval voting and that doesn't happen. You can run a hundred candidates and no one splits the vote. There is no point in even having primaries anymore, just run all your candidates in the general. Party becomes little more than an endorsement.
Libertarians don't have to run as Republicans to avoid splitting the vote with them, and then don't have to vote with Republicans on stupid wars or oil subsidies or whatever to avoid having a Republican run against them and hand the next election to a Democrat. Likewise with Greens vs. Democrats and anything else you like.
Proportional representation brings a bunch of different problems and is much harder to achieve in the US because it would require federal constitutional changes, whereas you can change the voting system in a state with a simple majority of the state legislature.
And different voting systems fix this. Suppose you have single representative per constituency with STAR voting. Then there is no "you didn't vote for this person" because you vote for everyone in degrees and the candidate who best represents the district wins.
Now suppose you're a minority constituency. You're 5% of the population, dispersed all across the country. With the existing system, a candidate willing to murder you in order to lower gas prices by 1% for everyone else can win the election with 95% of the vote. This is also the result you get with PR, because the "don't murder me" party gets 5% of the representatives, a coalition government forms in which they are not a part, and you get murdered.
But with STAR, the candidates who commit to not murdering you get the highest possible score form your demographic and the ones who want to lower gas prices get the lowest possible score. Since there can be a hundred candidates running, this will plausibly be the main difference between two of them, and a 1% difference in gas prices isn't enough to significantly change the scores people outside your demographic give to the other candidates. So the "don't murder me" candidates win everywhere and constitute the entire government no matter how the coalitions shake out.
In Czechia (where a pirate party is currently a part of the government) it was IMHO quite the reverse - the Czech Pirate Party mostly gained popularity by accenting ordinary center-liberal political themes.
The Pirate Party of Canada used to be quite active on r/CanadaPolitics. Once they fleshed out their platform they ended up overlapping heavily with the NDP and Greens (particularly the Greens).
I think many Pirate Parties have fallen into similar traps when they fleshed out their platform.
Yes, pretty much. There are Greens in Czechia but they are more left-progressive (compared to center-liberal pirates) and they are unacceptable for many because of their anti-nuclear position.
