Jeff Merkley Needs to Explain his Out Of State Campaign Expenditures

The new local online news organization Golocalpdx.com has published an analysis of campaign expenditures made by Jeff Merkley and found 78% of his money is spent outside Oregon, which blew my mind.  Furthermore, his campaign has stonewalled the news organization and:

"refused to answer any questions regarding his out-of-Oregon spending and refused to answer questions about his or his consultants' relationships/ownership with any of the companies receiving millions of dollars of campaign accounts."

 I await an explanation of this revelation, and I hope other local media picks the story up too.
