By late 2025, the No Tax Oregon campaign reported collecting over 150,000 signatures, surpassing the required number to qualify for the ballot. This rapid and extensive signature-gathering effort was noted for its scale and speed, highlighting Diehl's ability to mobilize grassroots support for his political initiatives.
