What we stand For

Our Platform

The Maricopa County Democratic Party has developed the following platform – a living doctrine that can be adjusted and changed with the times. We agree these important objectives align with the principles of our diverse party and constituents.

  • Diversity and equity for all are what strengthens our communities and party.
  • Private, for-profit prisons must be eliminated.
  • No border wall. No immigration ban. Stop the deportations. No human being is illegal.
  • Every citizen has the right to vote.
  • People’s voices and grassroots movements to elicit change cannot be ignored. The right to peaceably protest must be protected.
  • We must overturn “Right to Work” and build strong unions (both private and public sector) that will help provide better living wages for workers. Ban the box!
  • We believe in a strong separation of church and state.
  • Public education must be properly funded and teachers should receive the pay they deserve. Public schools are our priority – not vouchers.
  • The right to call for referendum is vital to free society.
  • Climate change is real. It must be addressed immediately.
  • Black Lives Matter.
  • All People should have equal status and protection under the law regardless of gender, race, disability/ability, religious affiliation or lack thereof, sexual orientation, or gender identity.
  • Women’s rights are human rights. The right to choose is essential to women’s rights.
  • Disability rights are civil rights. A barrier-free, inclusive, diverse community empowers and values each individual while creating autonomy, opportunity, and dignity.
  • Healthcare is an inalienable right and there should be universal healthcare for all.
  • Higher education is not a luxury. College, trade schools, and universities should be, as stated in the state constitution, as “nearly free as possible”.
  • We support the rights of all tribal people and their sovereignty rights.
  • Corporations are not people. Dark money must be removed from politics.
  • We support net neutrality. The internet must remain free from corporate control.
  • Equal pay for equal work.
