The Republican Party as we have known it is now officially dead. Flatline. The new party created by Trump in its stead must be called the Nationalist Party from now on.
Politico: “Suddenly, [...] it is Trump’s new alliance of angry populists that is ascendant — and on the precipice of dominance.”
Washington Post: “The rise of Donald Trump has baffled the so-called establishment of the Republican Party. It’s become just as confounding to the libertarians, conservatives, and ‘constitutionalists’ who used to be called the “Tea Party.” While Cruz had spent the days before these caucuses pre-spinning a loss, the size of the Trump victory challenged notions about who, exactly, was a conservative.”
Amanda Carpenter on CNN was realistic about the end of her party:
"I'm really struck in thinking about what a Donald Trump nomination would actually mean," she said. "I really think it's the end of the Republican Party. It's a natural effect. We've watched what's happened by a lot of people who have wanted to save power so badly they didn't listen, didn't listen, didn't listen to the grassroots. They didn't listen in 2010, they didn't listen in 2014 even though we won those midterm elections. Nothing changed."
