Why was it even close?

The Wobblies (International Workers of the World) lost a representation election in Minneapolis at a local fast food chain. The employer vigorously contested the election even hiring a well-known union avoidance consultant. The newsworthy question is why was this one close? The Wobblies have a history as a far left union, and recently have focused on organizing workers other unions have not targeted. The labor organization lost 87-85 with 2 challenged ballots. Even if the 2 challenged votes went its way, the union lost the election, because it could not establish its majority status. Nevertheless, it plans to object to the results claiming the employer engaged in unfair labor practices.
