If the Republican agenda is so unpopular, how does the party win elections? Partly by lying about its policies. But mainly the G.O.P.’s political achievements depend on identity politics — white identity politics. Exploiting racial resentment to capture white working-class voters, while pursuing policies that benefit only the wealthy, has been the core of the party’s political strategy for decades. That’s why, in an increasingly diverse country, Republican support has stayed overwhelmingly white.

In a fundamental sense, Trumpism is the culmination of that strategy. Commentators keep calling Trump a “populist,” but the only way in which he actually caters to working-class white voters is by appealing to their racial animus. He may be successful in doing so partly because it’s the only thing about his political persona that’s sincere: All indications are that he really is a racist.

His substantive policies, however, have followed the standard right-wing agenda: In 2017 he passed a huge tax cut, largely for corporations, that disproportionately benefited the wealthy, and almost succeeded in repealing Obamacare, in the process gutting Medicaid.

And these policies have endeared him to the G.O.P.’s money men. “Deep-pocketed Republicans who snubbed Donald Trump in 2016 are going all in for him in 2020,” reports Politico.

They’re doing so even though they know that Trump was installed in office in part thanks to Russian aid, that his financial entanglements with foreign governments pose huge conflicts of interest and that he consistently shows a preference for dictatorships over our democratic allies.

As I said, the modern G.O.P. is perfectly willing to sell out America if that’s what it takes to get tax cuts for the wealthy.

Once you accept this reality, two conclusions follow.

First, anyone expecting bipartisanship in dealing with the aftermath of the Mueller report — in particular, anyone suggesting that Democrats should wait for G.O.P. support before proceeding with investigations that might lead to impeachment — is being deluded. Trump is giving the Republican establishment what it wants, and it will stick with him no matter what.
