Leaders of two major unions, including the first to endorse Obama in 2008, said they have been betrayed by an administration that wooed their support for the 2009 legislation with promises to later address the peculiar needs of union-negotiated insurance plans that cover millions of workers.So will these unions stop supporting Democrats? Will these unions call for the repeal of Obamacare? If no to both, then these unions are mere puppets of the Democratic Party and their words are meaningless.
