All I know is the overwhelming majority of Conservatives/Republicans are against the US Supreme Court’s ruling on gay marriage.
Yeah, small government conservatism is definitely falling out of favor, I don’t think you’ll get any argument from anyone about that. After all, there were five conservative justices on the court, and only the oldest sided with the Goldwater conservative argument. The four newer appointees all sided with the position of the newer, more dominant conservative ideology. Reagan is revered among conservatives as a matter of tradition, but few conservatives would touch his policies with a ten foot pole these days.
