This idea has been merged with Ability to change my vote in ArcGIS Ideas.
There is an ArcGIS Idea upon which I made the unwise to decision to Demote. Since then I have discovered that I would far prefer to Promote that Idea because I've come to believe it is very important. Can we have the option to change a Demote into a Promote, please? If implemented please be sure that it turns a -1 into a +1 (and not just into a 0).
