July is usually one of the slower months for special elections and that is the case again this year.
The most interesting contest is next week's primary in Arizona's 7th congressional district, which became vacant with the death of Rep. Raúl Grijalva in March. It is a deep blue district, so the winner of the Democratic primary is highly likely to be the next representative.
There's just one election we're following this Tuesday. It is a primary for the one open seat in the Rhode Island State Senate.
