Donald Trump’s presidential campaign has been energizing and electrifying white supremacists, and their excitement is hitting new highs now that he is clearly the Republican Party’s presumptive nominee.

The neo-Nazi site Daily Stormer, which endorsed Trump two weeks after his immigrant-disparaging campaign launch, is filled with posts celebrating the GOP candidate’s victory this morning. “White men in America and across the planet are partying like it’s 1999 following Trump’s decisive victory over the evil enemies of our race,” says one post, which also celebrates that “[t]he Jews are in full-on freak-out mode.”

The site is also promoting a video parody in which Trump and other political figures are spliced into clips from the movie “300” and Trump is portrayed as “leading an army of the White race against the barbarian hordes.” Daily Stormer is also glad that Trump helped move his ally Alex Jones from “tinfoil goofiness” and into “nationalism.”

White nationalist Richard Spencer’s Twitter feed is similarly filled with celebratory gloating.

White nationalist leader Matthew Heimbach, chair of the pro-Trump Traditionalist Worker Party, recently celebrated Trump for having gone “full ‘America First’ for his foreign policy plan.” On his Daily Traditionalist show on Radio Aryan this morning, Heimbach and co-host Sven Longshanks praised the way Trump’s campaign has “opened up so much political space for nationalists” and made it easier for people in both the U.S. and Europe to say things that were previously impossible to say in public discourse.

Heimbach said Trump’s campaign has also helped his Traditionalist Worker Party’s organizing because areas in which Trump does well provide fertile ground for recruiting. There’s a need for long-term organizing, he said, and while Trump takes the beachhead, nationalists will provide the reinforcements.

The fires of nationalism, the fires of identity, the fires of anger against the corrupt establishment are arising all around Europe, all around America, all around the entire world. So we just need to strap in, because the future is gonna definitely be interesting, and I believe we could have a switch in our direction even more…Hail, Emperor Trump! And hail, victory!

The white nationalist website VDARE leads with an article by James Kirkpatrick celebrating the meltdown of the conservative “establishment” and the conversion of the Republican Party into a nationalist party. A few days earlier, after Trump’s wins in the so-called “Acela primaries,” Kirkpatrick declared that Trump “is creating a new opportunity for the American Right, which either needs to embrace nationalism and identity policies or suffer slow extinction in a Third World America.”
