There's no mention in the various stories at Politico that the controversial and expensive race between the Democrat Sinema and the black Republican Parker was spoiled for the latter by a libertarian candidate whose platform included open voter suppression.

The spoiler in the race may turn out to be Libertarian candidate Powell Gammill, who garnered more than 10,000 votes, despite urging voters during an October televised debate to stay home on Election Day in protest of the political system.
