| Updated: 10:35 p.m. Afraid that “party raiding” is interfering with Republicans’ selection of nominees in primary elections, the Utah Senate gave the final legislative stamp of approval to a bill limiting when voters can change their party affiliation. Republican senators voted 22-3 mostly along party lines Wednesday to pass HB197, which would prevent a voter from switching parties for nearly three months ahead of a primary election. If a voter decides to change party registration after March 31 of an election year, that change wouldn’t become effective until after the late June primary. Three Democrats present voted no and two others were absent. Sen. Gene Davis, D-Salt Lake City, was the only member of the minority to vote for the bill.
