Chrystal Ocean from Challenging the Commonplace posted a link to an amazing website that lets people vote in a British Columbia provincial election using the Single Transferable Vote system. It's easy to use. Just go Try BC-STV, click a riding, and rank your candidates from first preference to last. Once you submit your choices, the results are tabulated showing how others voted in that particular BC-STV riding and the candidates that would get elected.
Go to Try BC-STV. Have fun and tell your friends about the website and BC-STV!
