The endorsement by US Rep. Dennis Cardoza (D-California) of Obama today sends an extremely firm message to the Clinton campaign, and not only because he was, until today, a Clinton superdelegate.
The Field has learned that Cardoza is the first of a group of at least 40 Clinton delegates, many of them from California, that through talking among themselves came to a joint decision that all of them would vote for Obama at the convention. They have informed Senator Clinton that it’s time to unite around Obama, and that they will be coming out, one or two at a time, and announcing their switch between now and the convention if Senator Clinton doesn’t do the same.
Cardoza’s announcement, today, sent the message that the effort is serious and for real.
