New campaign finance filings show Nike co-founder Phil Knight gave at least $330,000 to Republicans running for positions in the Oregon legislature, with the largest share going to a Hood River candidate.  The Register-Guard reports that the wealthiest man in Oregon, Phil Knight, gave thousands in personal campaign contributions to seven Republican candidates in battleground districts last month, including an $80,000 donation to 52nd District incumbent Mark Johnson.  Knight’s other contributions went to another incumbent and five newcomers seeking open House seats, with the others receiving between $25,000 and $50,000.  It’s unusual for Knight to provide sizeable donations only to Republicans.  The last time he personally donated to Oregon legislative races was in 2012, when he gave $55,000 to 10 Democrats and $75,000 to 12 Republicans.  In 2014, he gave $250,000 to Democratic Gov. John Kitzhaber.  Knight didn’t respond Tuesday to a request for comment about his recent contributions.
