Out of curiosity; what do you Americans vote for? As a European, I am only familiar with the US presidential elections...
Every two years, we vote for our entire lower house of legislature (House of Representatives) and 1/3 of our upper house (Senate) so that each member there gets a six year term. The half of elections without a Presidental election are considered "mid-terms", because they are in the middle of the presidents term.
Each state also elects a governor, as well as a legislative body. The county (sub state divisions) and city level also have various elections. The states all vary when the elections occur, so that sometimes they line up other elections, sometimes not.
Some states also have judicial elections, which is as stupid an idea as it sounds like.
But, sad truth, due to the way that the lines for various districts are drawn, there are only like 4 elections in the country for the House that are actually close. And given how Senate seats are winner-take-all for the state, there are only a few that are really in play there as well.
Don't you guys also vote for local officials from mayors and town councillors and county officials down to judges, sheriffs, district attorneys, garbage collection department chiefs, etc.... ?? Or is it just in hollywood movies where district attorneys, sheriffs and judges are constantly worrying about being re-elected? Here in the old world the only ones elected in local elections are mayors and town/city councillors, and provincial/county level people. Lower officials than that are either appointed by whoever wins local elections or they get hired because they are the most qualified applicant for the job (well theoretically, sometimes they get hired because the are loyal party soldiers or because they are related to some local politico). Judges and police chiefs are appointed by the minister of justice but still with professional qualifications in mind (again... in theory).
