A key endorsement for Obama, a key dis-endorsement for Clinton

By Michael J.W. Stickings

1) NYT: "Representative John Lewis, an elder statesman from the civil rights era and one of Senator Hillary Rodham Clinton's most prominent black supporters, said Thursday night that he planned to cast his vote as a superdelegate for Senator Barack Obama in hopes of preventing a fight at the Democratic convention." (More from the AP here.)

2) Politico: "Two labor sources tell Politico that the giant Service Employees International Union [SEIU], which has been neutral through the primary, is on the verge of throwing its support to Sen. Barack Obama."

But I don't want to get too excited. It's awfully close in Wisconsin, and Obama is trailing Clinton by significant margins in both Ohio and Pennsylvania.
