ASL: "running for office"

For "running for office" you would use "COMPETE" and/or combine: VOLUNTEER+COMPETE.

I'd recommend fingerspelling "office" or just sign the specific position the person is seeking.

See: COMPETE
See: VOLUNTEER
See: OFFICE

Notes:
 

Note:  Jjust because we label a sign as "VOLUNTEER" doesn't mean the sign is limited to the same meanings as the English word "volunteer."
