SACRAMENTO, Calif. (AP) _ California gubernatorial candidates spent more than $28 million to win their parties' nominations four years ago. The 1998 campaign may make them look like paupers.

This year's four top candidates for governor have already spent $24 million, two months before the June 2 primary.

Multimillionaire Al Checchi has spent the most: $16 million of his own money. He's expected to spend another $2.5 million by the end of the month.

Rep. Jane Harman, who is running neck-and-neck with Checchi in the most recent poll, has spent about $4 million. She and her husband, a wealthy stereo manufacturer, have given the campaign all but $250,000 of the $4.5 million raised since she jumped into the race Feb. 4.

The third Democratic candidate, Lt. Gov. Gray Davis, has spent $1.35 million and has nearly $4.7 million left in the bank.

Attorney General Dan Lungren _ the likely Republican nominee _ has spent $2.7 million and has $3.7 million left.

A spokeswoman for the secretary of state's office didn't know the record for spending by candidates in a California gubernatorial primary race.
