Will California's Proposition 1 pass? Most likely

Summary

Proposition 1 is on the March 5th California ballot. It needs a 50% majority to pass. It authorizes $6.38 Billion in bonds to build mental health treatment facilities for those with mental health challenges. It provides housing for the homeless. It amends the Health Services Act to provide additional behavioral health services. It also shifts $140 million annually of existing tax revenue for mental health from counties to the state.

Regardless of its merits, Proposition 1 is most likely to pass.

The most recent poll conducted by the Public Policy Institute (PPIC) indicates that around 60% of likely voters are in favor. The poll sample size (over 1,000) translates into a probability of Proposition 1 passing at close to 100%.

The California legislature passed the underpinnings of Proposition 1 by over 80%. These included the Senate Bill 326 (which changes the allocation of funds between the State and counties) and Assembly Bill 531 (introducing the $6.4 billion bond to fund treatment centers).

Supporters have raised over $10 million. Opponents have raised only $1,000.

Except for The Orange County Register, all major dailies (LA Time, SF Chronicle, San Jose Mercury News, Sacramento Bee) support Proposition 1.

Given the above, Proposition 1 is most likely to pass.

Background

Proposition 1 is on the March 5th California ballot. It needs a 50% majority to pass. Proposition 1 authorizes $6.38 Billion in bonds to build mental health treatment facilities for those with mental health and substance use issues. It provides housing for the homeless. It amends the Health Services Act to provide additional behavioral health services.

The fiscal impacts are to shift $140 million annually of existing tax revenue for mental health from counties to the state and increase state bond repayment costs of $310 million annually for 30 years.

The polls

We uncovered four different polls on Proposition 1 conducted between November 2023 and mid-February 2024. These included:

You can see the polls results on Proposition 1 below.


Now, let’s prorate the Yes and Nos so they add up to 100%. We do this by taking out the Undecided.


Next, let’s explore the related polls statistics.


Within the above table, I reduced the sample size by taking out the Undecided. I then calculated the variance, standard deviation, 95% confidence interval, error margin, and MIN and MAX associated with the 95% confidence interval using standard statistics.

Probabilities of Proposition 1 passing

Even when focusing on the lower poll of February 13, the probability of Prop 1 passing is close to 100% as the table below indicates. The 60.8% mean proportion is 7.2 standard deviations above the passing threshold of 50.0%. This translates into a Prop 1 probability of passing to be very close to 100%.


Below, we explore the probability of Prop 1 passing at various percentage levels of in-favor or Yes votes.


As shown above, based on the most recent poll, there is over a 70% probability that Prop 1 will pass by an in-favor percentage as high as 60%, when it needs only 50% to pass.

Next, we will look at why Prop 1 is getting a pretty strong support that shores up its probability of passing.

Explaining the support for Proposition 1

Californians are painfully aware of homelessness (PPIC poll 72% see homeless nearly every day).


The large tent encampments have grown and become omnipresent within all California large cities.


Addicted homeless is a visual reminder that the status quo is not working.


About 80% of California polled likely voters support financial assistance for the homeless and converting vacant office space into affordable housing.


As of December 2023, office vacancy rates have gone through the roof in both San Francisco (32.1%) and Los Angeles (27%). These huge vacancy rates may represent an opportunity for converting vacant office spaces to affordable housing for the homeless. However, the economics of such conversion remains unclear.


Supporters and Opponents

Supporters include:

Opponents include:

When looking at supporters vs opponents, it looks like a fair fight. But, when we will look next at the campaign funds raised, it is not. This fight is over.

Campaign funds supporting Proposition 1

Based on recent data from Ballotpedia, Prop 1 supporters have raised close to $11 million, spent a bit more than $1 million, and have close to $10 million left in the bank. Hospital concerns have contributed a bit over $3 million.

Ballotpedia data as of February 22, 2024

By contrast, the opponents of Prop 1 have raised only one thousand dollars.

If campaign financing is any indication, you would expect that Proposition 1 is most likely to pass.

California Media's position on Proposition 1

Supports Proposition 1

Opposes Proposition 1

Conclusion for this section

The Media is split along partisan lines. The one major conservative daily, The Orange County Register, is against Proposition 1. All the other major dailies are in favor of Proposition 1.

Based on overall Media support, you would expect that Proposition 1 is most likely to pass.

California Legislature support for Proposition 1

The California Legislature introduced Proposition 1 through two bills:

Senate Bill 326 (SB 326), introduced in the 2023–2024 legislative session, was a legislation modifying the Mental Health Services Act (MHSA), revising the distribution of MHSA funds between State and counties. Formerly, the distribution between State and counties was 5% vs 95%, respectively. Senate Bill 326 changed the mix to 10%/90%.

Assembly Bill 531, also known as The Behavioral Health Infrastructure Bond Act of 2023, was a legislative act in California that facilitated Proposition 1 to be on the March 5th ballot. The bill aimed to fund the building of mental health and drug or alcohol treatment centers through the issuance of $6.4 billion in bonds.

As shown below about 90% of legislators voted in favor of Senate Bill 326 and 84% in favor of Assembly Bill 531. These represent dominant percentages, especially when you factor that the California Legislature has numerous Republicans who will reflexively vote against anything proposed by the California Legislature that is dominated by Democrats.
