They do.
Meet Heather Leung, a truly reprehensible woman who tried to run in Burnaby-North Seymour, the riding directly next to mine. She claimed that Homosexuality was a "perverted" lifestyle, that homosexuals "recruit" other peoples children to be homosexual since they cannot reproduce on their own, and that there was a serum that you could be injected with to turn you gay.
It took the Tories weeks to remove her as an official candidate, even though these statements had been circulating for years. When they finally did, she refused to remove her signs or anything because it was so late in the campaign that she would still appear as the Conservative candidate on the ballot paper.
She still got about 20% of the vote in her riding.
