Rep. Rick Larsen has joined the ranks of superdelegates supporting Sen. Barack Obama.
In a conference call with reporters this afternoon he called Obama a "tough and resilient" candidate and said Obama's victory in North Carolina and a near come-from-behind win in Indiana proved he can run strong though the fall.
Larsen said it carried a lot of weight that the Illinois senator "has energized and inspired my constituents like no other candidate."
Larsen also said it is up to Sen. Hillary Clinton to decide whether to campaign through the end of the primary season in June. He didn't feel the party would suffer irreparable harm at continuing but said it had become "very clear to me" Obama will be the nominee.
Six of Washington's 17 superdelegates remain uncommitted. Larsen said he did not know if any others would be making decisions or in the near future.
