From the AP report 'Sierra Club chooses establishment candidates in board election':

Sierra Club leaders beat back efforts by anti-immigration forces trying to gain control of the nation's largest environmental group, persuading members to defeat the challengers by a landslide in board elections...

An increasingly vocal faction of the San Francisco-based Sierra Club has advocated a tougher stance on immigration, calling U.S. population growth the greatest danger to the environment.

Leaders of that faction have accused the club's leadership of unfairly trying to influence the election by using club resources to back candidates picked by the nominating committee.

Lies by the "non-liberal" press didn't help. For instance, the lie above about the challengers being "anti-immigration." Sure, it's a step up from calling them "anti-immigrant," but it's still a smear. The challengers aren't "anti-immigration," they prefer restrictions on immigration. Maybe next election the press can be encouraged to lie less.
