It's pretty much everyone. It's just that everyone also knows you can't actually go into a political debate with "GIVE ME FREE STUFF" and expect to get very far. But of course we all want free stuff. I want free stuff. I've got the discipline to know better than to vote for it (because for one thing I know there is no such thing as "free"), but I damned well want it.
But of course there's plenty of BI advocates who want free stuff. You can find plenty of people musing on how they'd live on nothing but the BI in any conversation on HN, if they could.
