Here is the Arizona Forward Party argument for Proposition 140 that appears in the Publicity Pamphlet for the 2024 General Election (p248):

The Arizona Forward Party urges voters to say YES to Proposition 140, the Make Elections Fair initiative to adopt open, non-partisan primaries in Arizona.

Have you ever wondered why it seems that we always end up with two bad choices in our general elections? Polarized partisan politics and our current primary election system lead to the exclusion of good governance.

Our current “open” primary system is anything but open. Any voter can only see one-half of the available candidates: Republican voters only see Republicans, Democrats only see Democrats, and independent voters (34% of the electorate) can only see candidates from one legacy party per their designation.

This system disenfranchises many voters, with the exhausted majority failing to participate in the primary elections. This puts the decision of who appears on the general election ballot in the hands of 10% of each party--who tend toward the political extremes. Once elected, these candidates are unlikely to work across the aisle for fear of being perceived as weak, and being “primaried out” by an even more extreme candidate in the next election cycle. And so, we are doomed to have progressively more polarized elected officials as time goes on.

Open, non-partisan primaries can change that. By having all candidates appear on one primary ballot—regardless of party affiliation—voters have a choice of candidates that reflect a broader range of positions than the strict doctrines of the legacy parties. This will lead to ALL candidates being more responsive to the majority of Arizonans, and lead to better governance.

Please support Proposition 140 to make elections fair and make a positive change for Arizona.
