Tell everyone you know, then get them to tell everyone THEY know. What may make a difference now, even more so than a voluncation, is ensuring that every voter knows what the procedures are for voting in their state. With the procedural changes that many state legislatures have made, we need to make sure that people are properly registered and that they know exactly what they need to do to get their vote cast and counted.
Thank you for writing this. I hope everyone who reads it takes a voluncation between now and November.
