(Undated)  --  A strange political campaign charge is apparently driving a huge jump in Internet searches for a certain hairy mythical creature with strong ties to the Pacific Northwest.  The adult website Pornhub says Bigfoot searches are up eight-thousand percent since a congressional candidate accused her opponent of liking Bigfoot erotica.  Virginia Democratic candidate Leslie Cockburn leveled that charge at Republican Denver Riggleman in a tweet Sunday. Cockburn tweeted that Riggleman has been, as she put it, exposed as a devotee of Bigfoot erotica.  Riggleman says his opponent is getting the wrong idea from some jokes his friends posted on social media.  One showed a sketch of Bigfoot with a Censored label over its private area.
