Honestly there may not be a lot to learn regarding today's core Republican doctrines. Keep in mind I'm speaking of those in power right now vs. those Conservatives who would actually be good leaders like a Jon Huntsman. Moderate, decent Republicans seem to be dinosaurs as current Repubism is deeply rooted in anti-intellectualism, manipulation, and propaganda. The things we know are emotional issues. Abortion, brown people, non-Christians, gun laws, the public good. For every economic policy they claim to have they are 100% hypocritical about it. Example they claim competition, de-regulation, and small business are the future of America. Yet they go and push major monopolies to cripple smaller business in favor of anti-consumer giants like Verizon/Comcast/AT&T by legislating new regulations and laws to limit broadband competition and choice (mostly Southern states). They want to lower the minimum wage, eliminate worker rights, eliminate the social safety net, yet they want CEO's to be unhinged and able to consolidate as much of America's wealth as they want even if it kills the country. They claim to be the protectors of life, but only if they're unborn. Once you're born you have no human rights to affordable healthcare, and of course death and torture are just fine whether you're innocent or guilty ( once again a mostly Southern state mandate).
To understand what's going on I actual recommend reading more about Joseph Goebbels and Hitler's rise to power. Xenophobia and jobs programs are what led so many to join the Nazi party (with the critical aid of media). The parallels to Trump's campaign are startling. It's interesting how many Nazi's claimed "they only voted for Hitler because he promised jobs and better prosperity - we were so surprised when he followed through on his violent deeds." Trump supporters are the same way. I've seen so many tweets of Veterans that supported Trump are so surprised when he starts dismantling or stalling their social services, or marginal home owners confused why he's cutting their ability to make mortgage payments. Jobless middle America voted a Republican when Obama and Democrats tried to cover them when they lost their jobs via unemployment extensions. I mean, talk about voting yourself into destitution, Republican voters have been doing that for years. The trick is Republicans use Goebbels techniques masterfully, while at the same time covering its obvious parallels. Fox News, Hannity, Breitbart, Alex Jones, Rush Limbaugh - they're all part of the same machine. It might be decentralized but it's the same. The more this country crumbles and destroys itself the more powerful their voices become. 9/11 was the best thing that ever happened to help boost their careers. A peaceful and "equally" prosperous America doesn't need to live off hate thus they wouldn't have the ratings numbers nor the income they have vs. a country in conflict.
So I guess I don't have any concrete suggestions as I think every right-wing core leader writes stuff full of contradictions that normal people see right through. About the only policies that don't drown in their own hypocrocies are intolerance, guns, and consolidating wealth at the top. I think Reagan and Bush Sr. were the last powerful Republicans who were trying to do the right thing and weren't spending most of their time on media manipulation. But then again, Reagan had his own very bad stuff with Iran-Contra. Reality just doesn't have a field in current Conservatism. Is that 300 lb mud-trucking redneck really going to go work on the assembly line at an Apple factory? Heck no. He doesn't have the dexterity, speed and small fingers of a 100 lb. Chinese woman to work with tiny, cramped, electronics. But don't let that reality change the thought that Apple being forced to abandon China will fix America and bring them wealth. If it was really just about work they'd be out picking crops instead of us bringing in a million Hispanics to do the job. If they didn't support Republicans maybe those jobs could pay a decent wage, but they will continue to not see how their representatives work against them and manipulate their lives. For those on the far right, it's really a mind-boggling display of evil(?), and I don't think it has anything to do with "values", "philosophy", nor "solid policy." It's about wealth, control, and power. In all irony pretty darn close to the ruling classes of China and Russia. Except China actively invests in public infrastructure and housing.
