Utah has been the only state in which it is impossible for a candidate to get on a partisan primary ballot unless that party’s caucus gives that candidate substantial support before the primary. In 2014 the legislature passed SB 43 which sets up a procedure for a candidate to run in a primary, even if he or she doesn’t show substantial support at an earlier caucus.
However, on February 6, the Senate Government Operations & Political Subdivisions Committee passed two bills that would undo what the legislature did in 2014. SB 43 postpones the new system until after the 2016 election, and SJR2 would repeal the new system.
