Presumably the theoretical minimum of choices a voter could have in this election is two; President and Representative.
But many people will also be voting for a Senator, and/or a Governor, and/or a state rep, attorney general, 10 ballot initiatives…
… Where do people have the MOST choices they could make?
California tends to have all that, plus a dozen or so initiatives. There are 11 this year, and they have six candidates to pick from for president, plus eight more certified write-in choices. Counties will also have initiatives or propositions- looks like San Francisco has eight ballot propositions to wade through.
Actually, CA is a little light this time, with no Governor’s race. When the Governorship is up for election, several other executive offices such as Lieutenant Governor, Attorney General and Secretary of State are on the ballot as well.
As already implied, it would be difficult to determine, since many jurisdictions have local offices and initiatives. Local school boards are very common in addition to city councils, mayors, county supervisors, and various sorts of city inspectors in some places.
For one data point, in Maryland today I voted for POTUS, U.S. Senator, Representative, 2 Judges, 3 Board of Ed. seats, 7 state ballot questions, and 15 county charter amendments. So 30 separate choices total.
In Florida we had POTUS, senator, representative, at least 6 judges, water board, local senator, local representative, mayor, sheriff, tax collector, state attorney, probably a couple other local races I missed, 10 constitutional amendments, and at least 7 local referenda.
Today in Chicago I voted on 33 contested races, 58 judicial retention questions, two citywide advisory questions, and one state constitutional amendment.
I had 89 votes to make on my ballot in suburban Cook County…the judicial election / retention issue seems to put Illinois (or, at least, the Chicago area) near the top of the list.
