Kickstarter's in the US, no? Did you check out that WP link? I don't mean this as a "did you even read the article" jab, but you mention Labour, but this is about the US and the laws in the US mandate that those working under union labor agreements may be required to pay dues, yes, but may also be allowed to (effectively) specify that their funds may not go toward (most forms of) political spending, but only bargaining and member services.

Money is fungible; every dollar they get from you for bargaining and services, is a dollar they don't have to spend from other members, and can allocate to political lobbying.
But the thousands of companies I could work for have healthy competition and diversity of approach to issues. An industry-wide union has no competition and no diversity.

Say you were a Green supporter, and had a strong conviction against military intervention. How would you feel funding a union leadership that campaigns for Labour, following Iraq?
