“Salt Lake County is tripling the number of voting centers — from 12 to 36. “There will be no long lines this time, I promise,” Swensen said. . . .“If people are voting by mail, their ballot must be postmarked by Monday,” said Swensen.
Also, early in-person voting is available Monday — an extension allowed by a new state law replacing one that cut off early voting the Friday before an election. Sites for in-person voting Monday or Tuesday are listed online at vote.utah.gov.
