A check and memory makes it depressing. It seems that successful formation of political parties in the US depends on splintering from an existing party, and even then it's not successful. There's Theodore Roosevelts Bull Moose Party, then the Dixiecrats. Ross Perot's party was practically a flash--in-the-pan event, and I remember someone recruiting for another start-up party in or around 1992 that was not Perot's and which turned out to be out-there and not in a good way (no, I can't recall the name of the party). The latter tried to build a base on the local and state levels but failed.
It seems that successful party formation depends on existing infrastructure, though. That makes sense since any start-up party is going up against established political machines.
Not very encouraging.
Tuur, I am curious, are you in a 3ird party?
Your complaint is very true in the USA where the Congressional system is in place. Third party candidates are no more than spoilers. The reason that 3ird party politics does not work in the USA involves our congressional system. We are not parliamentary. Let me explain.
In Parliamentary countries, after an election, their political parties must join together to form coalitions so that they can have a majority and rule. In the USA, our political parties are already coalitions. We choose a faction within a political party during our 1st election called "primaries." The primary loosers have to choose to form a coalition around the primary winners.
Each party can have a wide variety within its coalition. The Democratic party has far left individuals like Bernie Sanders and more moderate individuals such as Joe Manchin (went independent 2 months ago). The Republicans have "
a coalition of conservatives, right-libertarians, populists, and centrists." (quote in blue taken from
https://en.wikipedia.org/wiki/Republican_Party_(United_States)"
In your OP, you are right. Third parties never stand a chance. They only serve a spoilers. Third parties are usually way to narrow to form coalitions and so are relegated to be a very distant 3ird place.
Tuur (the OP author), I think you might be looking at Parliamentary style politics. In Parliamentary politics you get more choices of political parties, but the Parliamentary parties are far more narrow on issues and are more like a faction within one of the major parties of the USA.
I would say that there are two major differences between the Congressional system and the Parliamentary system. First, you vote for a political party in the parliamentary system (and not a person). Second is the question of when the coalition occurs. USA Congressional politics have political parties that already have pre-existing coalitions. In the primaries we choose the personality that will represent the coalition. In Parliamentary politics, the parties form coalitions sometime after the first election. My point is that coalitions are formed in different ways in the Congressional and Parliamentary systems. However, in the end, coalitions must be formed with either democratic system, just at different times in an election cycle.
I watched the recent elections in France. In the first Franch election, the far right (anti-emigration party) won the election. Coalitions reacted to this win and shuffled their coalitions. The far left withdrew, and they voted for the moderate/left party. That coalition won the next election about 1 week later. In the end, after negotiations, repeated elections, and shuffling, Macron's smaller center party seems to have won. Macron's smaller centrist party had to negociate on their issues to form coalitions to win.
Nevertheless, I feel your pain. I too have chosen not to join either major political party in the USA because they include coalitions that include people who differ from me in world view. Well, that is the nature of coalition political parties. To be a part of a 3ird party might be self defeating, because I do not get to vote in primaries and have my say in either coalition. So I have to ask myself the question, do I wish to be a part in choosing the leader of a coalition, or do I want a political party that accurately reflects my world view. That is a tough choice.
At the end of your OP you say, "its not very encouraging." I completely understand that. While the USA rarely reflects my world view, I love the USA for its liberty. I get to think what I want, say what I feel like, and I truely do care about my country. If I desire to not be a part of one of the two political coalitions, that is my perogative. If I choose, I can refuse to vote. I get to turn my long warted nose up at all political parties inlcuding 3ird parties if I want. My ultimate loyality is to the King of Kings and Lord of Lords, the master of the universe, Jesus Christ. But until he returns, I do thank God for placing me in America and I will pray for my country and its leaders, Democratic or Republican.
