On January 10, the Oregon Secretary of State said he would put these candidates on the major party presidential primary ballots automatically: Democrats Clinton, Edwards, Gravel, Kucinich, Obama; Republicans Giuliani, Huckabee, Hunter, McCain, Paul, Romney, Thompson. The law says candidates are on the ballot automatically if they are mentioned in news media.
The Secretary of State also said he would delete any names on his list who withdraw, so presumably he will soon delete Duncan Hunter.
