Tuesday 20 May 2008: All 30 of Oregon's delegates to the Republican National Convention are allocated to presidential contenders based on the results of the voting in today's Oregon Presidential Primary.

• 30 delegates delegates to the National Convention are to be allocated to presidential contenders based on the primary vote statewide. A 3.5% threshold is required in order for a presidential contender to be allocated National Convention delegates at the statewide level.
• At the National Convention, the delegates are pledged to vote for the winner of the primary unless they are released by the candidate, the candidate receives less than 35% of the votes for nomination, or until two convention nominating ballots have been taken.

The 3 party leaders, the National Committeeman, the National Committeewoman, and the chairman of the Oregon's Republican Party, will attend the convention as pledged delegates by virtue of their position.

This is a vote by mail primary. State election officials will be mailing ballots out to registered voters between 2 and 6 May 2008 (18 to 14 days before the election); the voter has until 8 PM local time on the date of the Primary (20 May 2008) to return the completed ballot to either the county election office or a designated drop site: note that all mailed in ballots must have been received by that hour (postmarks do not count!). Voters who will be out of town during the period between the mailing out of the ballots and the Primary election may request an "early absentee ballot" from the county election official up to 45 days prior to the Primary (this deadline would be 5 April 2008): such a request may be made in person, by mail or by fax.
