Abel Maldonado's run for governor as of June 30 was in the red, and we're not just talking about Republican red.

When Maldonado's campaign previewed his midyear campaign finance report hours before he filed it late Wednesday night, it disclosed how much the former GOP lieutenant governor from Santa Maria had raised and how much cash he had on hand. Campaign officials said that Maldonado raised just over $314,000 and spent a little less than $318,000 in the first six months of the year, leaving him with about $44,600 cash on hand as of the end of June.

But once the official disclosure forms were released, they also showed more than $47,900 in outstanding debts as of that date, in effect leaving him $3,300 underwater.

A separate report shows Maldonado received a $27,200 contribution in mid-July, but it's unclear whether that lifted him into the black. It will be months before he must report his campaign's spending again.

His spokeswoman didn't answer an email and a call seeking comment Thursday.

Gov. Jerry Brown, who has not yet formally announced that he will seek re-election, raised $2.8 million in the year's first half and had more than $10 million cash on hand as of June 30.

Wednesday's report-filing deadline also offered snapshots of the battles shaping up in several Bay Area Assembly districts in which no incumbent will run next year.

As many as six Democrats might vie to succeed Assemblywoman Nancy Skinner, D-Berkeley, who will lose her 15th District seat because of terms limits. Former Obama administration official Elizabeth Echols of Oakland raised almost $85,000 in the year's first half and had almost $80,000 cash on hand as of June 30, with almost $18,000 in outstanding debts. Sam Kang of Emeryville, an economic-justice advocacy group's attorney, raised $74,000 and had $69,000 cash on hand, with about $4,000 in debts. Andy Katz of Berkeley, president of the East Bay Municipal Utilities District's board, raised about $56,000 and had about $49,000 cash on hand with $7,000 in debts. Tony Thurmond, a former Richmond councilman and school board member, raised more than $52,000 and had almost $36,000 cash on hand, with about $12,000 in debts. Peggy Moore of Oakland, the California political director of President Obama's 2012 re-election campaign, raised $30,000 and had $25,000 cash on hand with no debts. San Pablo Councilwoman Cecilia Valdez had not reported any fundraising as of Thursday.

Assemblywoman Joan Buchanan, D-Alamo, also faces term limits in the 16th District. Orinda Councilman Steve Glazer, a Democrat who was a political adviser to Brown's 2010 campaign, raised about $245,000 in the year's first half and had about $240,000 cash on hand but $2,000 in outstanding debts as of June 30. Dublin Mayor Tim Sbranti, a Democrat, raised about $112,000 and had about $101,000 cash on hand but $10,000 in outstanding debts. Danville Mayor Newell Arnerich, raised $50,000 and had $39,000 cash on hand but $7,000 in outstanding debts. Attorney Catharine Baker, a Republican from Dublin, had not reported any fundraising as of Thursday.

Assemblyman Bob Wieckowski, D-Fremont, intends to run for the 10th State Senate District seat, leaving his 25th Assembly District up for grabs. San Jose City Councilman Kansen Chu, a Democrat, raised about $170,000 in 2013's first half and had about $153,000 cash on hand as of June 30, with $1,000 in outstanding debts. Ohlone College Board of Trustees member Teresa Cox, a Democrat, raised about $16,000 and had about $15,000 cash on hand with almost $4,000 in outstanding debts. Milpitas Councilman Armando Gomez, a Democrat, hadn't reported any fundraising as of Thursday.

Assemblyman Paul Fong, D-Campbell, will be term-limited out in the 28th District. Campbell Mayor Evan Low, a Democrat and Fong's aide, raised more than $113,000 in the year's first half and had about $240,000 cash on hand as of June 30, with about $3,000 in outstanding debts. Both Cupertino City Councilman Barry Chang, a Democrat, and silicon chip processing engineer Michael Hunsweck, a Republican from Stanford, have declared their intent to run for the seat, but neither had filed fundraising reports as of Thursday.
