Today there are many different Factions of the Republican Party
There are people who call themselves “moderates”. Moderate is generally considered as average. Moderates are an average between Democrats and Republicans. You will find moderates in both parties. The Democratic Moderates tend to lean right. The Republican Moderates tend to lean left. They do not consider themselves as “extreme”, but often attribute this description to those who have differing opinions within their respective parties.
Another group prefers to be called “conservatives”. Conservatives generally oppose things like excessive taxing and regulation. They support things like a strong military. They often consider moderates to be RINOs. Moderates often consider conservatives to be extreme.
Neoconservatives are a group who came over from the Democratic Party. They are generally fiscally conservative, but they support an interventionist foreign policy. Paleoconservatives support a strong military for defense, but oppose preemptive wars.
And then there’s the libertarian wing of the party (small “l”). They favor a Constitutional Republic with minimal government interference, minimal taxes, and minimal regulations. You leave me alone and I’ll leave you alone. The libertarians are huge supporters of the free market, rather than socialism or crony capitalism.
These different factions of the party were more united while Ronald Reagan was president, but have since splintered so much that it seems like several parties within one party.
In Utah The Great Divide in the GOP has become even worse since the state legislature passed SB54 in 2014 which gutted the caucus/convention vetting system. Now Democrats are flocking to the Republican Party to either run as Republicans, or to support their liberal candidates who are running as pretend Republicans. They don’t have to support the party platform, let alone the party bylaws or constitution. They just have to buy enough signatures to get on the ballot. Even Bernie Sanders could run as a Republican in Utah now, thanks to this election law. This will create even more RINOs in a One-Party State.
