Your examples show another way Rand can finesse communicating the issues (by leaving most of his beliefs unsaid). The problem, though, is that we've already been through a campaign where Rand finessed communicating the issues. We found out that doesn't work, in terms of building a winning coalition. And the candidates who did do better talked mainly about issues other than taxes and fiscal restraint of government---they spoke about immigration, protecting the national interest from trade to refugee policy, and cultural issues.
Our next liberty candidate needs to talk about the issues the voters actually want to talk about (not the stereotypical ones we think they want to talk about), BUT to talk straightforwardly to them with pro-liberty answers, NOT finesse them. If they want to talk about jobs, talk about liberty approach to job creation and a growth economy. If they want to talk about health care, talk about the liberty approach to health care and health freedom. And so on---talk plainly about what issue comes up, and when it does, things are not to be left unsaid.
