The Hugo is no longer a representative of the best of sci fi and fantasy. They are now excluding many others because their personal political views are different, completely ignoring the quality of the work. They are giving awards to authors for espousing the "right" politics for works that are far below the standards the award should represent. For example, Scalzi's "Red Shirts" got best novel. It's not a bad story, but it's not a great story, and Best Novel must be a great story.
When the conservative authors asked people to consider books on a list, representing conservative authors, they were accused of attempting to manipulate the vote. Not they didn't. They asked people to read the books and stories on the list and consider them. Manipulating the vote was when some higher ups in the organization publicly stated that straight white men should not be given awards, they should all go to women of color. At the height of this fiasco, they skipped giving out some awards entirely because the obvious winners didn't fit their political views.
Perhaps they've come to their senses since then, but I wouldn't know as I no longer pay attention to the award and a book with the "Hugo Winner" label on it is not the selling point it once was.
