Julian Zelizer : The lack of a libertarian candidate is emblematic of the right’s shift away from free-market fundamentalism.

Zelizer says the left is on an evangelizing mission to impose its values across society unless resisted.

Frida Ghitis: Social righteousness as a prerequisite for liberty is an insight our Founding Fathers understood.

She says libertarians and conservatives will accuse conservatives of wanting to enact a Christian theocracy, but that’s a lazy smear.

Ghitis argues that in a free society, the state must proactively promote social virtue to prevent society from descending into cultural degradation.
