Tuesday is Election Day, and although no state or federal offices are on the ballot, there are plenty of municipal and school races of local significance.

Minneapolis, of course, is making its first plunge into ranked-choice voting for city offices. Under this system, voters designate first, second and third choices for each office, with lower-ranking preferences coming into play if first-choice votes alone don't produce a winner. Races on the ballot include those for mayor, City Council, Park Board, and the Board of Estimate and Taxation. There also is a ballot question on the composition of the Board of Estimate and Taxation.

Voters in St. Paul, meanwhile, will be deciding whether to adopt ranked-choice voting for future elections. They also will be electing a mayor and school board members.

Elections are also taking place in many other cities and school districts, with seats at stake and some levy referendums in the mix.

SOME NUTS AND BOLTS:

Who can vote? Generally speaking, anyone who is a U.S. citizen, is at least 18 years old and has lived in Minnesota for 20 days immediately before Tuesday's election is eligible to vote.

When to vote: Polls will be open from 7 a.m. to 8 p.m. Tuesday.

Where to vote: For your polling place, contact the Secretary of State's office -- 651-215-1440 or www.sos.state.mn.us -- or go to the Star Tribune's online Voter's Guide at www.startribune.com/politics. Election information is also available from many city and county offices.

To register on Election Day: If you are not registered at your current address, you may register at your polling place on Tuesday. To do so, you must provide proof of your identity and where you live.

You may use as proof any of the following:

• A valid Minnesota driver's license, Minnesota learner's permit or Minnesota identification card (or receipt for any of these) with your current name and address in the precinct.

• A tribal ID containing your name, signature and photo and address in the precinct.

• A valid student ID, including your photo, if your college has given a student housing list to election officials.

• A valid registration in the same precinct under a different name or address.

• Notice of late registration sent by the elections office (if you turned in a voter's registration application late).

• Someone who is registered in the precinct where you live who can confirm your address with a signed oath (this is so-called "vouching"; note that vouched-for voters cannot vouch for others).

• An employee of a residential facility where you live who can confirm your address with a signed oath.

Or, you may provide a photo ID plus a current bill with your current name and address in the precinct. Acceptable photo IDs (which may be expired or have an old address or no address) include a Minnesota driver's license, a Minnesota ID, a Minnesota post-secondary student ID, a tribal ID, a U.S. passport or a U.S. military ID.

Acceptable bills (delivered by mail or electronically) must include your name and your address in the precinct, and may include:

• Any of the following utility bills due within 30 days of the election: phone (land-line, cell, VOIP, etc.); TV (cable, satellite, etc.); Internet services; electric, gas, water, sewer or solid waste, or a rent statement that itemizes utilities and is dated within 30 days of the election.

• A current student fee statement that contains the student's valid address in the precinct.
