Here is the piece where I raised the claim fifteen months ago: http://www.dailykos.com/story/2015/7/9/1400647/-Hillary-Clinton-s-Western-Sahara-Policy-Will-Be-a-General-Election-Issue
If you don’t want to read it at Daily Kos, you can read it at my little “change the world” hobby website: https://gardenvarietydemocraticsocialist.com/2015/07/11/hillary-clintons-western-sahara-policy-would-be-a-general-election-issue/
(Here’s the initial piece a week before when I first raised the scandal–in the context not of politics but of my anti-capitalist democratic internationalism:
http://www.dailykos.com/story/2015/07/05/1399252/-Anti-Capitalist-Meetup-Part-3-on-the-Need-for-Anti-Capitalist-Democratic-Internationalism
https://gardenvarietydemocraticsocialist.com/2015/07/06/part-3-on-the-need-for-anti-capitalist-democratic-internationalism/)

My outspokenness on this issue indirectly resulted in the first of my two suspensions from Daily Kos. A Clintonite was so abusive to me when I raised the Western Sahara matter in a comment to a Hillary Clinton glorification piece that I carried the wound to a future internet encounter where I accused the person of being a shill working for the Clinton campaign with no evidence, other than circumstantial and logical that is, which isn’t good enough to even ask the shill question. (I don’t feel like looking through my thousands of comments for the glorious encounters, but they were doozies I can assure you.)

And now, it is indeed a general election issue, being raised not only by her opponent– https://www.google.com/amp/s/amp.cnn.com/cnn/2016/10/21/politics/clinton-morocco-trump-pay-for-play/index.html
–but also by the MSM.

A writer in the Atlantic says:

[T]his exchange about Morocco, first reported by The New York Post, is the clearest example yet in the emails posted by WikiLeaks of the type of arrangement that people find most, well, icky about the Clintons. Bill and Hillary wanted a deep-pocketed donor to make a large contribution and foot the bill for a ritzy conference, and the king of Morocco wanted access to the woman who, then as now, was the leading candidate to be the next president of the United States. The Clintons didn’t apparently care that, as the Post noted, Morocco had a spotty record on human rights. The State Department has cited the Moroccan government for widespread corruption, and the government-owned mining company that paid for the CGI meeting has been cited for its own human-rights abuses.

P.S. I am still following the Chomsky approach in this election and holding my nose and voting for Clinton as the LOTE: http://caucus99percent.com/content/rounding-error-hillarys-prescient-pricey-even-18-million-freudian-slip
