Proposition 437 Explained: Why Yuma Wants to Change Candidate Signature Calculations

Proposition 437 would change which election's turnout is used to calculate nomination-petition signature requirements for City of Yuma candidates. It would keep the same 3%–5% range. The proposed change is from the preceding general municipal election to the preceding primary municipal election, as described in the City Council record for O2026-018.

That difference is small in wording but meaningful in arithmetic. A percentage of one ballot total can produce a different signature count from the same percentage of another ballot total. The measure does not name one fixed number of signatures that would apply forever. It changes the election used as the calculation's starting point.

The current rule

Article IV, Section 6 of the City Charter addresses nomination for a primary election. It requires signatures from qualified City electors totaling at least 3% and no more than 5% of the valid ballots cast in the preceding general municipal election. The current Charter text identifies both the percentage range and that general-election basis.

The rule refers to valid ballots cast, not the number of registered voters, the City's population, or votes received by an individual candidate. These measures can be different. Using the wrong one would change the calculation even if the percentages were copied correctly. A plain-English description therefore needs both the percentage and the specified ballot count.

The nomination process concerns access to the primary ballot. It is different from the vote totals or percentages used to determine an election winner. A candidate's petition signatures are not votes cast for that candidate in the election, and collecting enough valid signatures does not establish that the candidate will win.

The proposed rule

Proposition 437 would substitute the preceding primary municipal election for the preceding general municipal election. The proposal retains the 3% minimum and 5% maximum. It also retains the Charter language about qualified City electors, submission in accordance with state law, and the City Clerk's certification of the required signatures.

The underlying ballot total is often called the denominator or calculation base. Changing that number can change the resulting signature totals without changing the percentage range. Describing Proposition 437 as cutting the percentage requirement would therefore be inaccurate. Describing it as removing nomination petitions altogether would also be inaccurate.

The City’s June 23 notice summarizes the same change. It identifies Article IV, Section 6 as the Charter provision affected and explains the switch from general-election ballots to primary-election ballots. That limited description is more precise than saying the measure rewrites all candidate-qualification rules.

The documented 2026 example

For the 2026 candidate cycle, the City stated that candidates needed a minimum of 998 and a maximum of 1,664 valid signatures from qualified City electors. Its 2026 candidate announcement gives those figures and explains that they used the existing general-municipal-election basis. These numbers describe the 2026 requirement, not a later requirement under Proposition 437.

The distinction between a published requirement and a prediction is essential. The proposition does not say that 998 or 1,664 will become a permanent threshold. Nor are those numbers the size of a promised reduction. They are a concrete example of the signature range candidates faced in the documented cycle under the existing method.

The City's announcement points candidates to its handbook and Clerk's Office for filing information. This explainer uses the announcement to verify the historical range. It is not a filing packet for a future candidate, and it does not translate the proposal into an official future signature requirement. That later requirement should come from the City's materials for the relevant cycle.

An arithmetic example, not a turnout forecast

Suppose a hypothetical general municipal election had 30,000 valid ballots and a hypothetical primary municipal election had 10,000. Applying 3%–5% to 30,000 yields 900–1,500. Applying the same percentages to 10,000 yields 300–500. These are invented round numbers used only to show the mechanism; they are not Yuma turnout figures or City-issued requirements.

The example changes only the denominator. Neither percentage is reduced, yet both numerical endpoints become smaller because the hypothetical primary ballot total is smaller. If the two ballot totals were equal, the arithmetic would produce equal endpoints. The formula depends on the actual figures, not on the labels primary and general by themselves.

Future signature totals would therefore depend on valid ballots actually cast in the relevant preceding election. The proposal does not guarantee one constant reduction across all cycles. It would be inappropriate to take this illustration, or a rounded turnout estimate, and present it as the number an actual future candidate must submit.

Why the City says it wants the change

The City states that a 2020 Charter amendment moved municipal elections to even-numbered years and that candidate elections have occurred in presidential and gubernatorial cycles since 2022. Its Council report says the resulting higher ballot totals increased the number of nomination signatures candidates needed, with some judicial and Council candidates falling short.

The City also states that legislation advancing primary dates moved the nomination deadline ahead of the Yuma County Fair, which had been a place for candidates to meet residents and collect signatures. These are the City's explanations for the proposal. They are presented as the Council report's account, not as an independent finding about why any specific candidate failed to qualify.

The report characterizes the change as reducing the signature burden. The legal mechanism is narrower and clearer: apply the unchanged percentages to primary-election ballots. Distinguishing the mechanism from the City's expected benefit helps readers evaluate the proposal without assuming that every prediction about candidate participation will follow automatically.

What a yes or no vote changes

A yes vote would adopt the proposed Charter amendment. A no vote would leave that proposed amendment unadopted. The question does not ask voters to choose a candidate, decide who should win a future race, or waive the signature-certification process. It asks which preceding municipal election should supply the calculation's ballot total.

It also has no role in the $30 million expenditure-base adjustment proposed in Proposition 436. The two measures are listed for the same November 3, 2026 General/Special Election, but one concerns candidate nomination and the other concerns spending authority. A judgment about either proposal does not determine a voter's judgment about the other.

What remains unknown

The official materials establish the proposed wording change and the unchanged percentages. They do not establish how many people would choose to run in future elections, how many would submit enough valid signatures, or whether particular contests would become more competitive. Those outcomes depend on decisions and circumstances beyond the denominator alone.
