High-profile Arizona campaigns will suspend some activity this week following the death of Sen. John McCain, who dominated the state's political landscape for decades.
McCain was just one of 11 U.S. senators in the state's 116-year history.
Primary voters will decide Tuesday on the nominees in races across all levels of government.
A key primary race is for U.S. Senate as Sen Jeff Flake is retiring. Republicans seeking the seat are Rep. Martha McSally, former state Sen. Kelli Ward and former Maricopa Sheriff Joe Arpaio. Seeking the Democratic nomination are Rep. Kyrsten Sinema and Deedra Abboud.
Arizona law requires the governor of the state to name an appointee of the same political party to fill McCain's seat.
