Look at post 127, the GOP doesn’t do much in the way of trying to appeal to full conservatives, they give a little lip service, do some gun stuff, wave the flag a little, but then they do like post 127.
There is no pool of voters out there in the democrat party that are eager to become republicans for conservative economic theory and Ayn Rand, but they can be appealed to on the eternal issues of family friendly, culture friendly, society friendly, social issues.
Democrat voters in the main aren’t going to switch away, because many are convinced that liberty comes through government instead of through themselves.
But there’s plenty of largely unaffiliated folks and true independents who don’t believe that, yet also don’t like the perceived moralistic bent of the GOP.
