I just got a press release from the SEIU touting the pro-labor types who are being considered as vice presidential prospects, among them Senators Sherrod Brown, Amy Klobuchar, Jim Webb, Claire McCaskill and Montana Gov. Brian Schweitzer. But there was an unexpected name -- SEIU Secretary-Treasurer and Change to Win chair Anna Burger. As a lifelong progressive activist and the first woman to head a major American labor coalition, Burger is a highly accomplished, admirable individual. But she simply isn't a realistic veep choice: She's too lefty, has never held an elected office or served in government, and as a public speaker, I've found her hit or miss. Furthermore, her deep-seeded economic populism, frankly, hasn't been embraced by the Obama campaign to date.
