A slate of Aurora school board candidates that won election last month were outspent by some of their rival campaigns — including in the final days of the race — but benefited from big spending by a union-backed independent committee.

Outside groups that backed the winning slate spent more overall during the campaign, but wound down as pro-education reform groups picked up their spending in the last period right before the election. Those efforts were not enough to push their candidates to victory.

According to the last campaign finance reports turned in on Thursday and covering activity from Oct. 26 through Dec. 2, Gail Pough and Miguel Lovato spent the most from their individual contributions.

Together Pough and Lovato spent more than $7,000 on calls, canvassing and consulting fees. Both candidates were supported by reform groups and had been reporting the most individual contributions in previous campaign finance reports.

But it was the slate of candidates endorsed by the teachers union — Kevin Cox, Debbie Gerkin, Kyla Armstrong-Romero and Marques Ivey — that prevailed on election night.

How much did candidates raise, spend?

  • Gail Pough, $12,756.32; $12,328.81
  • Lea Steed, $1,965.00; $1,396.16
  • Kyla Armstrong Romero, $7,418.83; $3,606.12
  • Kevin Cox, $2,785.54; $2,993.07
  • Miguel Lovato, $16,856.00; $16,735.33
  • Jane Barber, $1,510.32; $1,510.32
  • Debbie Gerkin, $4,690.00; $4,516.21
  • Marques Ivey, $5,496.50; $5,638.57
  • Barbara Yamrick, did not file

The slate members spent varying amounts in the last few days before the election. For instance, Cox, who won the most votes, spent $403 while Ivey who recorded the fewest votes of the four winning candidates, spent $2,056.

Most of the slate candidates’ spending went to Facebook ads and consulting fees.

The four also reported large amounts in non-monetary contributions. Collectively, the slate members reported about $76,535 in non-monetary contributions, mostly from union funds, to cover in-kind mail, polling, office space and printing. All four also reported a non-monetary contribution in the form of a robocall from the Arapahoe County Democratic Party.

Other financial support for candidates, through independent expenditure committees, showed that the group Every Student Succeeds which was backed by union dollars and was supporting the union slate, spent less in the last days than the reform groups Raising Colorado and Families First Colorado which were supporting Pough and Lovato.

Overall, the independent expenditure committee groups spent more than $419,000 trying to sway Aurora voters.

Incumbent Barbara Yamrick failed to file any campaign finance reports throughout the campaign.
