(Portland, OR)  --  A circuit court judge is ruling that Multnomah County can put campaign contribution limits in place.  Multnomah County Circuit Court Judge Eric J. Bloch ruled Monday that campaign contribution limit of 500 dollars per individual does not violate the First Amendment right to freedom of speech.  The ruling follows a years-long back-and-forth on campaign contribution limits in the courts after Multnomah County voters overwhelmingly approved the limits in a 2016 ballot measure.  The Oregon Supreme Court upheld the limits last April and sent the issue back to the circuit court for further review.
