Here are Idaho presidential primary results from the Secretary of State’s page. Idaho Republican rules mean that Ron Paul will get 4 delegates. The Democratic primary is just a beauty contest, since Democratic delegates were chosen earlier by caucus.
The Libertarian and Constitution Parties are also entitled to their own primaries in Idaho, but neither party chose to participate. In any event, Idaho won’t print up a primary ballot for any party if that party has no contests for any office. Although both minor parties are nominating candidates, the single candidate who filed in each race is deemed to have won the primary.
