(Burns, OR) -- Voters in another Oregon county have approved an advisory measure showing they want to become part of Idaho. Officials say 63-percent of voters in Harney County approved the measure. They join seven counties that have also voted in favor. More counties are expected to vote next year. The Greater Idaho effort would make much of Central, Eastern and Southern Oregon part of Idaho. The measure would have to be approved by the Oregon legislature, the Idaho Legislature, and Congress to happen.
