Oregon ballots are due in just three weeks, and the most contentious issue voters will decide is, arguably, Measure 97.  

This ballot measure would increase taxes on companies with more than $25 million in annual Oregon sales, thus raising $3 billion a year for schools, health care and services for senior citizens.  

The campaigns for and against Measure 97 disagree on one basic point: Whether corporations that pay the new tax will pass the cost on to consumers.   Like many voters, OPB senior political reporter Jeff Mapes wonders whether he’ll pay more — and set out to answer that question.
