Congress' Superdelegates Have Picked, But Stay Mum

Most of the 80 unpledged Dem superdelegates in Congress have privately chosen a candidate, and one of Barack Obama’s key Senate surrogates claims most have swung his way, Politico reports. It’s “a matter of timing,” Missouri's Claire McCaskill said. “They would like someone else to act for them before they talk about it in the cold light of day.”

Indeed, though a Hillary Clinton aide tried pushback (uncommitted lawmakers “are concerned about Sen. Obama’s electability”), lobbying at the Capitol has fallen off recently, and even Hillary-backing Sen. Robert Menendez admits conversations are now “about making sure everyone still feels loved and wanted.” Obama's campaign is set to reveal several new superdelegate endorsements today, Time adds.
