If it has helped you, great. My experience has been that I have heard pitches for countless "magic devices" over the years that end up in a closet somewhere because they don't really fix anything. This sounds like another one of those devices.
Nothing scientific but most of the people I know who live in NY and are republicans understand their vote is worthless in a Presidential election here, we vote mostly for local representatives. I think the all or nothing (except Maine and Nebraska) is understood by most though they may not understand it's conducted through the Electoral college.
I would think most republicans in CA realize their vote is worthless in a POTUS election but I could be wrong.
We're many years off from a 3-4 party system because the two main parties seem to only agree on one point, that the addition of a 3rd party would not be in their best interest. It would take someone that is moderate, with huge public appeal, like Reagan, to attract enough voters from both parties to make a 3rd party viable.
Gary Johnson is pulling 10% from the Republicans, hardly a threat to either party overall but he will make it near impossible for Trump to win.
