(KTRS) – State lawmakers are hammering St. Louis County election directors over problems in last week’s elections.

The Post-Dispatch reports that election officials say the problems were the result of several factors. Among them is a new requirement that touch-screen machines had to be used for the presidential primary on March 15. Officials say there was not enough time to collect and reprogram machines before April 5.

Another issue they said, the county has 90 municipalities and uses more than 320 separate ballot styles.
