Very cool to see the report I coauthored with @JarredCuellar on Prop 50 & Latino representation mentioned in the LA Times today! Thanks @AndreaSanFlores for the mention 😊

5/5 We also have an informative study by @CaltechLCSSP postdoc @RaqCenteno and @calpolypomona prof @JarredCuellar on how Prop 50 might affect Latino political representation in CA. https://t.co/srVLH7Jkum

1/5 Are you trying to figure out Prop 50? What to know more about what is going on with mid-decade gerrymandering? We've got you covered! You have questions, we have answers in the following four posts. @CaltechLCSSP

Want to see the full analysis? You can read the full report here: https://t.co/AkCFVzokDV

Big takeaways include: - the number of Latino-majority districts will remain the same (16 vs 16) - the number of Latino influence districts will increase (6 vs 8) - CA-41 will become a new Latino-majority district in LA County

Excited to share that a new report I coauthored with @JarredCuellar on Prop 50’s impact of Latino voters is out today! You can read about it in today’s @politicoca CA Playbook. We analyze the potential impact of Prop 50’s proposed maps on Latino voting & representation in CA ⬇️

FIRST IN PLAYBOOK: MAPPING LATINO POWER —#Prop50 would not only maintain but enhance Latino voters’ power in California House races, political scientists at @Caltech (@RaqCenteno) & @calpolypomona (@JarredCuellar) conclude in a new analysis. https://t.co/XZjSGhWsTD via @politico

A new report shows that Prop 50 would maintain 16 Latino-majority congressional districts but gain two additional Latino-influence districts (CA-20 and CA-48) A major change is the creation of a new Latino-majority district (CA-41) in Los Angeles County. https://t.co/Ge3e0wdYlH

🚨 New working paper! 🚨 Happy to share my new data on affective polarization by party across states, CDs, counties, and towns from 2009-23. Key point: polarization is not just an individual trait... contexts and electorates can be "polarized" too! 1/ https://t.co/NdqU7FijYR
