We know. Parties are a corruption of the way the government is supposed to work (on paper anyway), they’re privately owned, beholden to nobody, and there are no laws that force them to follow their own internal rules AFAIK.

The corrupting power of political parties was known even by the first president, but they instituted no laws against them or restricting their influence and autonomy, and it was even allowed to have a voting system under which political parties are systemically favoured (FPTP).

Because the country was owned by rich assholes from the jump.
