Wu owes much of his fundraising success this cycle to outside out-of-state donors, who made up more than two-thirds of the individual contributors these past three months. Only 38 of 143 individual donors to his campaign this quarter live in Oregon. As the first Chinese-American ever elected to the House, Wu enjoys significant support from the Asian-American community nationwide, who account for much of his fundraising so far this cycle. Wu has said that he has sought treatment for the mental health problems he had last year, but continues to face criticism. As a result, he is gearing up for the most significant challenge to his reelection in his six terms. His two announced primary challengers so far -- Avakian and state Rep. Brad Witt, cited the congressman's questionable mental state when announcing their candidacies. Democratic State Sen. Suzanne Bonamici has also expressed interest in running for the seat. Her husband served as a longtime personal attorney to Wu, but quit in April when his wife announced she was seriously considering a bid. But, there's also a growing possibility that if Wu gets several primary challengers, the group could split the anti-Wu vote, allowing the incumbent Democrat to win another term.
