The deadline is upon and the election season is set to officially begin: Tucson City Council and mayoral candidates must turn in their nominating petitions by 5 p.m. tomorrow.

Here’s how the races are shaping up so far:

Mayor’s Race

Democrat Jonathan Rothschild filed his signatures on May 9. A potential primary opponent, Democrat Marshall Home, filed his signatures today, but is expected to face a legal challenge over his eligibility to run for mayor.

Republican Shaun McClusky has a 12:30 p.m. appointment at the Tucson City Clerk’s Office to turn in his signatures tomorrow. His Republican rival, Ron Asta, tells The Range today that he thinks he’ll have enough signatures to file, but he’s still collecting them to have a cushion in the case of a challenge.

Two Green Party candidates, Dave Croteau and Mary DeCamp, are preparing to file the necessary petitions to quality for the ballot.

Independent mayoral candidate Pat Darcy has set a 4 p.m. appointment to turn in his signatures tomorrow.

Ward 1

Democratic incumbent Councilwoman Regina Romero turned in her petitions on May 4. Her primary opponent, Democrat Joe Flores, turned in his nominating petitions last week.

There is no Republican on the ballot in Ward 1, so the primary will likely decide the race.

Ward 2

Democratic incumbent Councilman Paul Cunningham turned in his petitions earlier this month. Republican challenger Jennifer Rawson turned in her signatures last week.

Ward 4

Democratic incumbent Councilwoman Shirley Scott turned in her petitions on May 2. Republican challenger Tyler Vogt turned in his signatures last week.
