Huntsman’s personal financial disclosure report also lists a debt of between $15,000 and $50,000 for a "property tax bill" owed to Washington, D.C., where he bought a home after returning from his stint as ambassador to China.Huntsman’s campaign has been mired at the bottom of the polls and reportedly has struggled to raise money. And he has already indicated that he loaned it "a little bit" from his own fortune "to prime the pump," raising the importance of his net worth on the future of his bid.Huntsman campaign spokesman Tim Miller could not immediately answer questions about how much Huntsman had loaned or contributed to his campaign, or whether the initial campaign loan came from the Zions bank loan. Miller did, however say that the Washington property tax bill had been paid, explaining the Huntsmans "have no tax liability currently. That was a routine tax bill that was owed during the reporting period. It was paid immediately upon notice after his return from China," where he had been serving as the Obama administration’s ambassador.Huntsman owns a "residential rental unit" in Coronado, Calif., worth between $1 million and $5 million, according to the report, which also shows that he, his wife and their dependent children hold tens of thousands of dollars’ worth of bonds from various Utah municipal government agencies. Meanwhile, Huntsman’s dependent children own between $5 million and $25 million in stock in a holding company that is entirely invested in the family’s chemical company.The Office of Government Ethics, which issues and oversees the reports, requires politicians to list assets and income for themselves and their spouses and dependent children but only requires broad value ranges.The figures in Huntsman’s report appear to peg him as the second-richest candidate in the GOP presidential field behind Mitt Romney, the former Massachusetts governor. When Romney’s campaign filed its personal disclosure report with the FEC, it provided a slightly more precise range for his wealth: between $190 million to $250 million.Candidates for federal office are allowed to contribute unlimited amounts to their campaigns. Romney loaned his unsuccessful 2008 presidential campaign $250,000, eventually writing off the loans as contributions. Romney has so far led the 2012 GOP presidential field in fundraising and has given no indication that he intends to loan cash to his current campaign.Speculation swirled in Republican finance circles from the moment Huntsman got into the race about whether and how much he was prepared to invest in his campaign, as well as about how his campaign might be boosted by his father, Jon Huntsman Sr., and the executives of the chemical company he founded, Huntsman Corp.Late last month, Huntsman Corp. executive Thomas Muir formed a super PAC called Our Destiny PAC to boost Huntsman’s presidential campaign. Unlike contributions to federal campaigns, which are capped at $2,500 per person, super PACs can accept unlimited funds from people and corporations, and, though Huntsman Corp. tried to distance itself from Our Destiny, the PAC’s ties to the company led to predictions that Huntsman’s father and corporation executives would heavily fund the PAC.
