Right to a secret ballot

Is the right to a secret ballot established in the US Constitution? It doesn’t seem to be in any direct and obvious fashion. But it is certainly a right that people seem to think they have? Could Kansas, say, pass a law saying all ballots must identify the voter casting the ballot and this information is publicly available?

If it’s not in the Constitution directly, has the Supreme Court made any specific decisions on this matter?

I have heard a legal expert state that ballot identity could be used in court if the validity of an election is in question. That would involve a case of voter fraud, or ballot counting error where the results could swing an election one way or the other.

I could see courts readily overturning such a law as you propose on the basis that it will deter voting, but I don’t know how that it could be considered unconstitutional. Perhaps that right to privacy we’re supposed to have would be used.

It’s not mentioned in the constitution. This is an issue left to the states. More info at wikipedia: Secret ballot - Wikipedia

There was a case, ever so long ago, where an election was in question, and a judge asked various voters how they had voted. Some tried not to answer, saying the secrecy of the ballot was a right. The Judge said that they didn’t have the right…

(And I don’t remember what the final upshot was.)

It wasn’t even an American idea.

Can you imagine all the problems if it wasn’t a secret ballot?

Outright purchasing of votes because they can be verified, employers looking up who their employees voted for, family members checking up on other family members, etc, etc…

Although it’s called the Australian ballot, according to Wiki, France was first, and the US and Netherlands had it before Australia.

And of course, they had secret voting in Ancient Greece for ostracism.

We don’t have to imagine. All we have to do is look at history.
