New Jersey Gov. Chris Christie says the Senate race in Delaware was "a missed opportunity" for his fellow Republicans to pick up the seat long held by Democrat Joe Biden.
Tea party favorite Christine O'Donnell won the GOP nomination in an upset over moderate Rep. Mike Castle. But she lost the general election Tuesday to Democrat Chris Coons.
Christie says he was proud to have endorsed Castle.
Christie told NBC's "Meet the Press" that "I think Delaware was a missed opportunity to have a really good U.S. senator."
Sen. Jim DeMint (R-S.C.), the conservative kingmaker who backed a number of tea party candidates heading into Tuesday's elections, said that it's "a very silly thing to say" that tea party candidates cost the GOP control of the Senate. Delaware Senate nominee Christine O'Donnell "was so maligned from Republicans that she didn't really have a chance," DeMint added.
