Both parties want our corrupt system changed. I hope it happens. It’s a failed system.
What is more corrupt? Crossing over to vote in your opponent Parties worst/most easily beaten candidate?
Or electing delegates who resolve contested election choices from within the Party?
The General election is coming up in November. That is where your “one man/one vote” takes place.
Either get involved with your local Party to change things, or stop bitching about the results you did nothing to prevent.
