Howard Dean, who campaigned for president opposing single-payer and ran the DNC opposing single-payer, and launched an activist campaign opposing single-payer, now says that it was “a terrible mistake” for Obama not to begin by proposing single-payer. But is Democracy for America duty bound to push for whatever terrible mistake Obama proposes? Shouldn’t a so-called grassroots group make fewer such mistakes than an elected official. Shouldn’t such groups push the elected officials to better positions rather than dutifully obeying the official and rallying for whatever halfway step has already been approved?
