If the issue was that important to people, they should have registered to vote earlier on. Only a small percentage would have been between houses / in a complicated situation, etc. Instead, so many left it to the last minute that the website crashed (yes, blame for that all around). They were then handed an extra two days.
For all the sound and fury north of the border, the Scottish turnout was pretty low - again, if the issue was that important to you, you should have bloody well got out and voted!
There is a quite widespread attitude that all one has to do to effect change is vote online or possibly phone in or text one's vote. What absolute balls. Get up off your arse and take your right to vote seriously!
