It's crept on us, but tomorrow is local election day. It'll be only the third time that the Single Transferable Vote system has been used in Scotland for nationwide elections. Instead of marking a cross on the ballot paper, we'll be using numbers to rank the candidates in order of preference. With the Scottish Tories seemingly on the march, it's now more important than ever that pro-indy voters use all or most of their preferences to rank every non-Tory candidate ahead of every Tory candidate - and, for that matter, to rank every non-unionist candidate ahead of every unionist candidate. If you're still unsure about why that's the case, the following video guide may help - it's a collaboration between myself and the amazing Phantom Power, creator of the recent Journey to Yes series. Feel free to pass it on to anyone who may find it useful. The direct link to the video on YouTube is HERE.
