AZ SB1189

Adopts the National Popular Vote Interstate Compact as Arizona law, allowing Arizona to join an agreement with other states to elect the president by national popular vote rather than the Electoral College.

Agreement takes effect only when states possessing a majority of electoral votes (270 or more) have enacted it in substantially the same form.

Once effective, each member state's presidential electors must be appointed to the slate that wins the national popular vote total (combined votes across all member states), regardless of which slate won in that particular state.

In case of a tie for national popular vote winner, each state appoints electors to whichever slate won the most votes within that state; if the winning slate has too few electors nominated, the presidential candidate may nominate replacements.

Member states may withdraw from the agreement at any time, except withdrawals occurring within six months of the end of a president's term do not take effect until after the next president is qualified to serve.
