Someone define social conservative in specific terms that can reviewed argued accepted or discarded?
Someone define conservative in a meaningful way as well.
Trouble is terminology while useful hardly fits any single person, Romney moved far to what is defined as social conservative and he lost. It would seem the title requires something other than what it evokes in the mind and in the values of American voters. But what is that.
All I can do is share my definition with you.
'Conservative' in this context means a person who has a set of principles that push them to oppose the change of a set of conditions from what they have and like now to one that they do not like or trust. As there are different sets of issues, social, financial/economic, and security issues, there are derived sets of conservative social positions, conservative economic positions, and conservative national security views.
It gets a little more complicated when you consider that many of the things that 'conservatives' want to keep today are things that were successful leftist agenda items of the past, like government regulation of marriage or free trade economics.
I prefer to look at the issues from a more traditional perspective, and that would be of a Catholic American conserevative circa 1965.
So in my view social conservatives hold to gun rights, free speech rights, civil rights, economic freedom, are pro-life, in favor of reasonable regulation to keep markets sane and pro-worker (look up Distributism sometime), and hold a Biblical Christian moral view.
Such people are now locked out of the GOP power center in the RNC as Wall Street and the RINOS have long controled that institution, and grass root efforts from the state level was all that kept the GOP a viable avenue for soc-cons.
Hope that helps.
