Clinton vowed to continue campaigning, and won convincingly in primaries in West Virginia on May 13, and Kentucky on May 20 where Appalachian voters strongly preferred her over Obama. However, Obama was able to clear a victory in Oregon on May 20, which allowed him to clinch the majority of pledged delegates. Obama gave a speech in Des Moines, Iowa, the state that propelled his candidacy, in which he stated, "You have put us within reach of the Democratic nomination for president of the United States of America." Clinton advisers said they would appeal to the DNC's Rules & Bylaws Committee to have the Michigan and Florida delegations seated. However, even under the most favorable seating arrangement, she would not have been able to take a lead in pledged delegates and would have had to rely on superdelegates to win the nomination. On May 31, the rules committee accepted the Michigan state party's 69-59 distribution of pledged delegates and restored half votes to Florida's and Michigan's delegations. This resulted in a net gain for Clinton of 24 pledged delegates. Obama remained significantly ahead, with a lead of 137 pledged delegates before the Puerto Rico primary on June 1.
