WASHINGTON, D.C. — U.S. Rep. Bryan Steil (R-Wis.), chairman of the Committee on House Administration, sent a letter Monday expressing concerns about a coding “glitch” that erroneously marked an unknown number of voters as having voted in Nevada’s Presidential Preference Primary (PPP), when in fact they had not. Under the current system, Nevada counties each night upload voter registration data that is used to execute code creating the statewide voter registration file that users can see online.
