I don't think the non expert voters not understanding the security is that big of a concern. Assuming that the security undisputed amongts experts, the media could convey this to the general population (absent some well supported opposition like climate science faces). At this point, the security points that need to be conveyed to the voters are relatively simple: 1) The receipt you are given may be used to confirm that your vote was correctly counted. Here is a list of websites/programs that you can use to verify your receipt. 2) It is impossible to use your receipt to prove to a third party how you voted. If we could get major news source (New York Times, CNN, Fox News, etc) to publish their own tools for (1), then I suspect that should give a fair amount of credibility for the general public. The problem I see is that any technical system of plausible deniability I can think of, would require that a voter is able to forge a receipt that would correctly validate as the incorrect vote. Otherwise, if an attacker wanted to verify that Alice voted Democrat, he could assume she voted Republican and attempt to verify the receipt.
