It's a bit more complicated like that. Come November, most Americans will having voting choices for at least four different levels of government, with some of those levels have multiple branches and some of those branches having multiple branches of their own. Many will also have direct democracy questions that are on the ballot as a result of voter initiatives or referendums which result in laws being made out side of the legislature or local government.
It wouldn't be unlikely for someone to be voting for President, Senator, Congressman, Governor, State Senate, State Legislature, County Board, Sheriff Mayor, and City Council, all of which occupy separate divisions of government. That's not including the various State offices (Attorney General, etc.), County offices, judges, school board, and any laws that are being put directly to the people to vote.
Also, some states require by law for electors in the electoral college to vote as they've been instructed to by the voters, but not all do.
