Sen. Barack Obama pocketed two more of his party’s superdelegates Friday.
California congressmen Jim Costa and Dennis Cardoza are endorsing the Illinois senator, according to a statement released by his campaign.
...Costa said electability had helped drive his decision. "In my opinion, it is clear that Senator Obama will be the strongest presidential nominee for the Democratic Party," Costa said in the statement released by the campaign.
