The following is all regarding primaries:

California, Alaska, and Louisiana have Ranked choice voting, in a way.

Alaska you can vote for ranked choice for presidency. (Top 4)

Louisiana, you vote for anyone, the ballots are not separated, so whoever wins 50% supposedly goes on (Top 4)

California is Top 2.

Notable mentions: Nebraska and Washington both allow top 2 voting as well regardless of party officialiation, but NOT for the presidential election yet.

If someone sees part of this wrong, let me know so I can correct it, but last I knew that's how different some of our states are.
