The race for Montana superintendent of public instruction remains too close to call as Yellowstone County continues tallying votes two days after the general election.
    
With most votes counted, incumbent Denise Juneau led by less than a percentage point over Republican challenger Sandy Welch.
    
Yellowstone County elections registration clerk Barb Cox said Thursday that officials hope to have all votes tallied by the end of the day.
    
Repeated problems with the county's three vote-counting machines delayed the results in the state's most populous county. Cox said the machines were running Thursday morning and a technician was on hand in case they had more problems.
    
Both Juneau and Welch have expressed confidence in their ability to win. Welch says she will seek a recount if the final tally is close.
