This is an interesting and highly cited read from PolitiFact.
The article carefully looks at the evidence and cites a variety of experts.
The conclusion is that there are no white nationalists at the White House although the four experts believe several players are close. For example, Steve Bannon is cited as a ‘nationalist’, rather than a ‘white nationalist’ although the article recognizes that the two are pretty close.
For me, the article is splitting too many hairs, talking to too many experts. There’s too much cancatonation of opinions and not enough rigorous analysis.
My conclusion is simple, the Far Right of US politics is currently in power in America and this is both bad for the US and the world. Debating which brand of Far Right politics is of little concern to those threatened by the ugly repression. Surely, this would be supported by the editors of most mainstream liberal newspapers around the world?
For a more comprehensive and intellectual analysis, see ‘Radical Right US’ or the ‘Alt Right‘. Another perspective might be to look at alternative definitions of fascism. Finally, for a detailed review of the international research literature on ‘radical right wing politics’, open this link.
