(UPDATED, 2:10 p.m. Saturday, to reflect a loan to Holli Woodings’ campaign.)

In three statewide races, Democratic candidates enjoy a significant fundraising advantages heading into the final weeks of the campaign.

Democratic gubernatorial candidate A.J. Balukoff raised — and spent — more than $1.8 million on his bid to unseat GOP incumbent Butch Otter.

However, the accountant, prominent businessman and Boise School Board member self-financed the bulk of his campaign. Meanwhile, Otter raised more than $600,000 during the summer, and heads into the campaign home stretch with more than a 10-to-1 advantage in cash on hand. Otter also holds a 24-point lead in a CBS/New York Times/YouGov poll released Oct. 1; Otter was up on Balukoff, 57 percent to 33 percent. (Details from Emilie Ritter Saunders at Boise State Public Radio.)

For Democrats, the fundraising advantages were more clear in two open statewide races.

Through the summer, state superintendent’s candidate Jana Jones continued to pad her fundraising advantage over Republican Sherri Ybarra, as the candidates vie to succeed outgoing Republican Tom Luna.

In the race succeed three-term Secretary of State Ben Ysursa, Democratic state Rep. Holli Woodings of Boise has built a sizable fundraising edge over state Rep. Lawerence Denney, R-Midvale, a former House speaker. But Woodings boosted her account by making a $90,000 loan to her campaign.

For statewide candidates, a moment of truth came Friday, with campaign finance reports due by the day’s end. The reports cover the period from May 31 through Sept. 30 — providing the best and most current snapshot of candidate fundraising heading into the final weeks of the election.
