Michael Scherer notices that Palin and Trump have had kind words for one another:

Trump was once a booster of Canadian-style health care. Palin sees such approaches as akin to death panels. Trump wants to impose a 25% tariff on China. Palin is a big free-trade booster. Trump supported the Obama bailout of the auto companies, saying he thought “the government should stand behind them 100%.” Palin has compared the government involvement in Detroit to spread-the-wealth socialism. But let’s not dwell on policy. The fact is both are tripped up by the press.

And so they are one. And that very fact is what makes each the model of the modern Republican populist.
