After all, what is the modern GOP? A simple model that accounts for just about everything you see is that it’s an engine designed to harness white resentment on behalf of higher incomes for the donor class. What we call the Republican establishment is really a network of organizations that represent donor interests because they’re supported by donor money. These organizations impose ideological purity with a combination of carrots and sticks: assured support for politicians and pundits who toe the line, sanctions against anyone who veers from orthodoxy — excommunication if you’re an independent thinking pundit, a primary challenge from the Club for Growth if you’re an imperfectly reliable politician. To a very casual observer, it may look as if this movement infrastructure engages in actual policy analysis and discussion , but that’s only a show put on for the media. Can you even imagine being unsure how a Heritage Foundation study on any significant issue will come out? The truth is that the right’s policy ideas haven’t changed in decades.
