It’s certainly possible to take the Warren analogy too far; Brat doesn’t have the same devoted following as Warren or her Ivy League academic prestige, and he lacks a parallel position within the conservative firmament. But it’s not a bad comparison, as far as it goes. And it touches on some of the ways that liberal populism and conservative or libertarian-tinged populism often overlap—the distrust of elites, frustration with those in power, and anger over the ways that big government and big business, so often assumed to be titanic opponents, work in tandem against the interests of the masses.
It also suggests the political power of this populist critique, even on the right. In recent years, liberals have successfully channeled anger against the joining of businesses interests and political power, but Republican politicians have not been nearly as effective in their attempts to do so, despite the current of anti-elite sentiment that runs through the Tea Party. There are many reasons why the GOP hasn’t been as successful (its reliance on corporate donors, its professional connections with corporate lobbying groups, the fact that many of its candidates are themselves part of the business class), but one reason why is that criticism of business, big or small, is simply not part of the identity the GOP has built for itself over the last several decades. That’s not the language it speaks; the GOP is the party that represents business, not the party that criticizes corporate power.
