So, you're claiming cheating, backing it up with nothing. The whole electoral system is "cheating" from the "Purple Party" known as the Repwe'llfuckyouupocrats Party.
The third party in the USA has one state House seat. That's it. In all of Federal and State legislatures, executives, they have ONE elected representative. In Germany, a country that is like three times smaller, the third party has 118 seats in FEDERAL GOVERNMENT.
Even the
South Schleswig Voters' Association with 55,000 votes at the 2021 German Federal election has more federal seats (it has one) than the third party in the USA, the USA which goes around the world claiming to be introducing democracy to the likes of Afghanistan, Iraq and Venezuela (by taking down the democratically elected leader, bizarrely).
