Hedlund got about 17.86 percent of the vote to Clark's 17.43. (Gildea, the first place finisher for the seat, got 53.44 percent).
I think the voters got it right here. While Clark's campaign was hard fought, she dedicated the lion's share of it to trying to get one of her opponents disqualified and to challenging the word "incumbent" on the ballot. I think some of that time might have been better served doing what is incumbent on all candidates -- making the case for why they are the best choice. The publicity surrounding the various court challenges gave Clark some name recognition, but also may have rubbed some voters the wrong way.
By contrast, Hedlund concentrated on what she would potentially add to the mix -- years of experience as a trial court judge. Whether or not you buy Hedlund's argument that the high court needs someone with her background, it's a more constructive approach.
