From the Article:

Milwaukee voters have a good chance of finding a contested primary, potentially with high stakes, on their ballot Tuesday.

There are 10 state-level partisan primaries on city of Milwaukee ballots Tuesday.

While candidates are technically running for the party’s nomination, a handful of primary races will actually determine who wins the seat come November. With few Republicans running for office in a Democratic stronghold like Milwaukee, some winners will coast into the general election unopposed.

Our candidate guide notes which races will be determined by the outcome of Tuesday’s partisan primaries. Uncontested races are not included.

The majority of the races on the ballot are for seats in the Assembly, where representatives serve two-year terms. The only Senate race is a rematch of the special election held in District 4 last month.
