Secretary of State Kate Brown is reminding voters time is running out.

"The deadline to register to vote is Tuesday April 29th via paper with the county clerk's office is by the end of the business day and to register online you can sign up by 11:59 if you have a drivers license.  I would encourage you not to wait until the last minute."

The May primary will decide which candidates face off in November for the U.S. Senate, Governor and Oregon's five congressional districts  -- along with several local ballot measures.
