Voters in eight of 10 Oregon counties approved a local measure aimed at bolstering the gun rights of residents, delivering widespread victories to an effort championed by militia groups.

The so-called “Second Amendment Preservation Ordinance” declares that those living in counties that approve it have the right to own semi-automatic weapons and high-capacity magazines, regardless of state or federal law. The measure appeared on the ballot in Baker, Columbia, Douglas, Jackson, Klamath, Lake, Lincoln, Linn, Umatilla and Union counties.

The ordinance also empowers sheriffs in those counties to determine if state and federal gun laws are constitutional and whether to prohibit local resources from being used to enforce them.

Partial returns show that the measure passed in all but Jackson and Lincoln counties.

The effort was organized by an Oregon gun rights group called the Committee for the Preservation of the Second Amendment. But it drew broad support among members of two militia groups, the Three Percenters and Oath Keepers, who campaigned and organized for the ordinance across the state.

Here’s a look at the results.
