Damon Linker at The Week says the GOP should be less worried about Donald Trump himself and more worried about why he appeals so much to the Republician base:
The GOP’s Trump problem goes all the way down to the roots of the party — the grassroots.[…] that faction’s roots go back much further than 2012 — all the way back to the origins of the modern conservative movement in the right-wing populism of the postwar John Birch Society and similar groups. They were a ragtag conglomeration of ideological radicals animated by rage against various actors, forces, trends, and policies in mid-20th-century American life: the New Deal, Big Government, communists, negroes, elites, decadent city folk, Catholics, Jews, immigrants, feminists, homosexuals, and secularists. Some feared them all, others focused on one or a few. All of them saw the world through a fog of paranoia and conspiracy.
The populists are the now base of the party — its most loyal and devoted members, surpassed only by super-rich donors for influence among the party’s leading politicians and strategists. Candidates for president have no choice but to woo this base, to legitimize its obsessions and flatter its prejudices. And the underdog candidates, meanwhile, pin their entire campaigns on these voters, hoping that the flattery will pay off in a surge of support, catapulting them to prominence.
That’s how we’ve ended up with a vulgar blowhard like Donald Trump riding high (almost certainly for a brief time) in the polls. Trump’s policy positions (to the extent that he’s bothered to articulate them) place him on the far-right flank of American political culture.
Patrick Healy and Maggie Haberman make a case in their NYT article that “Hillary Clinton’s Economic Agenda Aims at a Party Moving Left.” The hope is that “Mrs. Clinton is revealing her natural political self: a blend of progressive and pragmatic, an apostle of government policy as a force for change, and a more left-of-center leader than her husband.”
