SAN MARCOS -- Wal-Mart supporters are outspending their opposition by 10 to one in the contentious campaign over Proposition G, campaign disclosure statements filed with the city Friday show.

San Marcos 1st! reported $86,000 in campaign contributions, all of which came from Wal-Mart. The retailer's contributions of $30,000 and $56,000 were the only ones the committee received during the filing period, which covered Jan. 18 to Feb. 14. Roughly $77,000 in payments were reported.

The group is campaigning for Prop. G, a referendum on the City Council's August vote allowing the construction of a Wal-Mart at Rancho Santa Fe Road and Melrose Drive. The store's approval has created controversy among San Marcos, Carlsbad and residents of nearby unincorporated areas.

"We've been upfront that our campaign would be supported by Wal-Mart," said Luanne Hulsizer, the chairwoman of San Marcos 1st! and wife of San Marcos Vice Mayor Mike Preston. Some San Marcos residents have offered financial support, but she declined such offers, she said Friday.

"We're on track as far as our campaign strategy," she added. She would not disclose the campaign's budget, but said it wouldn't be affected by the opposition's spending.

By contrast, the opposition group SaveSanMarcos.org, reported $8,514 in campaign contributions from Jan. 1 to Feb. 14. Formerly named Citizens for Responsible Growth in San Marcos, the group was criticized for a $30,000 contribution from the United Food & Commercial Workers that helped force the referendum on the ballot. The new group focused on the campaign has not received financial support from the union.

Among the payments listed on the most recent statements for San Marcos 1st!: $12,639 went to The Greensburgh Group of Costa Mesa for polling; $2,348 to Cogs South of Santa Ana for signs; $1,275 to Post International for sign posting. $10,000 to the Jack Orr Co. for consulting; $3,080 went to campaign worker Lawson Chadwick.

The group made a number of payments to other companies which totaled: $3,799 for newspaper advertisements, roughly $9,000 for postage, $1,625 for slate mailers and nearly $25,000 for campaign literature.

The $31,000 legal tab for Wal-Mart's failed challenge to the referendum is still unpaid. No other accrued expenses were listed.

San Marcos 1st! also turned in two independent expenditure reports listing $1,182 to replace vandalized signs and $1,650 for campaign worker salary and mileage. Hulsizer would not say who the campaign worker is, but said her own work has been pro bono.
