Libertarians vs Social Conservatives

Instapundit has collected several links in an interchange between Ramesh Ponnuru and Ryan Sager prompted by Sager's TCS column.

WILL THERE BE A SPLIT between libertarian and social conservatives? Ryan Sager says that libertarians were poorly received at CPAC, which produced this response from Ramesh Ponnuru, this reply from Sager, and this rejoinder from Ponnuru. Libertarians' influence, of course, has been reduced by the split over the war among libertarians, but I think that a shift toward religious conservatism is likely to cost the Republicans votes. As I warned in Reason, people on both the Left and the social-conservative Right are exaggerating the power of religious conservatives, and that poses a real risk for the GOP.

To which I add this link from the Volokh Conspiracy:

While some libertarian political activists are certainly Republicans and Democrats, the existence of the Libertarian Party ensures that there are fewer activists and fewer voters in each major party coalition than would otherwise exist. Therefore, each party's coalition becomes less libertarian. I do not mean to exaggerate the extent of this effect. But even a handful of political activists in local and state party organizations can make a big difference. Whatever one thinks of the initial creation of the Libertarian Party, its continued existence seems to be a mistake for libertarians.
