Minnesota Senator Amy Klobuchar today became the second female Senator to endorse Barack Obama. Hillary Clinton has six. Obama says it's alright with him if Clinton stays in the race until the August convention, but many Democrats don’t feel that way. Tennessee Governor Phil Bredesen says the super-delegates ought to get together in June. Bill Clinton's reassurance yesterday to Democrats worried about the risks of a nominating campaign that drags on until August has not resolved the anxieties of many party leaders, and they're meeting in the modern equivalent of smoke-filled rooms. That's according to Politico.com in a story co-authored by David Paul Kuhn.
