The Republican party runs on several broadly unpopular or unwise policy platforms (anti-abortion, anti-weed, anti-welfare, anti-healthcare, anti-immigration, anti-science) and is hesitant to actually implement any of them for fear of igniting opposition.
Recently they’ve taken the side-channel of stuffing the courts and then legislating from the bench, since judicial appointees are immune to voter pressure.
Time will tell how this all plays out for the Republican party. In the short-term, it causes tremendous damage to our institutions.
In the long-term, my best guess is that the current Republican platform will collapse within 10-20 years as the current leadership ages out, and there will be a phase change where the Republican platform recrystallizes around a more modern set of conservative values that appeals more to younger voters. The party itself will likely survive because the two-party system is too stable.
