Presidential candidate Michael Dukakis picked up more endorsements in Utah Tuesday and supporters opened a campaign headquarters in Salt Lake City.

State Democratic Chairman Randy Horiuchi; Rep. Wayne Owens, D-Utah; and Salt Lake County Commissioner Dave Watson all endorsed the Massachusetts governor.The endorsements aren't just words, they mean delegates. Horiuchi is already a delegate to the Democratic National Convention. Owens and Watson hope to be selected as delegates.

Former Democratic Gov. Scott M. Matheson and his wife, Norma, endorsed Dukakis last week. Mrs. Matheson is Utah's national committeewoman, so she is already a delegate, and Matheson said he will run as a delegate in the State Democratic Convention.

Thus, Dukakis has already picked up four or five delegates out of the 27-member Utah delegation to the national convention.

Horiuchi said, while the other Democratic candidates all have something offer, he's going with Dukakis because he has the hands-on experience of running government.

Dukakis' headquarters are at 543 E. Fifth South. The telephone number is 355-9160.
