The "Don't talk about it in public" issues

Earlier I posted about real political issues and "hot button" issues. Since then it came to me that there is a third class of political issues, the "don't talk about it in public" issues. Second Amendment rights, decriminalization of marijuana, repeal of the Digital Millennial Copyright Act, reform of patent and copyright law, net neutrality, and tort reform, come to mind. There are probably others. These are real issues, that effect citizens directly. But for some reason, fear of offending the interest groups that support them, or journalists too clueless to understand them, or something, you never hear a candidate speak out on these issues at all. There are plenty of voters who care about these issues. Maybe the Republican party should take a public stand on some of them.
