**At least 7 donors (or donor groups) in Spencer L. Duncan's pre-general campaign finance report (covering July 25–Oct 23, 2025) have direct ties to GO Topeka and/or the Greater Topeka Chamber of Commerce.**

These organizations are closely linked—they operate together under the **Greater Topeka Partnership** (same address: 719 S Kansas Ave Suite 100, Topeka, KS 66603). GO Topeka is the economic development arm focused on business growth and opportunities, while the Chamber handles advocacy and policy. No standalone "GO Topeka" entity appears as a donor, but the ecosystem (including the Chamber PAC and Partnership board/leadership) shows clear support.

Here are the confirmed related donors from the Schedule A pages you provided (with dates, amounts, and ties):

1. **Greater Topeka Chamber PAC** — $2,000 (09/25/25, Page 3 of report)  

   Direct donation from the Chamber's political action committee (same address as the Partnership). They also publicly endorsed Duncan.

2. **Dr. Shekhar & Jayashree Challa** (listed as Doctor) — $500 + $1,500 = **$2,000 total** (09/24/25 and 10/16/25)  

   Dr. Challa serves as Chair of the Chairs Council / board leadership for the Greater Topeka Partnership.

3. **Amanda Chavez-Thomson** (General Manager) — $250 (10/14/25, Page 5)  

   Chamber Chair and board member of the Greater Topeka Partnership.

4. **John Dicus** (Executive) — $400 (10/09/25, Page 8)  

   Past Board Chair of the Greater Topeka Chamber of Commerce and active Partnership board member (often tied to Capitol Federal).

5. **Marlou Wegener** — $100 (09/23/25, Page 2/3)  

   Elected Director on the Greater Topeka Partnership board (also recognized with Partnership awards).

6. **Impact Marketing Group** (Consulting) — $200 (10/16/25, Page 7)  

   Listed as a strategic investor/partner with the Greater Topeka Partnership.

7. **Curtis Sneden** — $100 (08/04/25, Page 1)  

   Former President/leader of the Greater Topeka Chamber of Commerce.

**Additional notes on potential ties** (not as direct/confirmed as the above):  

- Natalie Haag (General Counsel, $100 on 10/09/25) has Chamber PAC leadership ties.  

- Several business/development donors (e.g., Abraham SN LLC $1,000, Morse Inc. $500, FYPM LLC $1,000, Bellaire Center $500, Capitol Advantage $100) are pro-growth entities that typically engage with GO Topeka's economic development programs, but lack explicit board/PAC-level connections in quick checks.

These 7+ represent strong backing from Topeka's business, economic development, and leadership community—totaling several thousand dollars in itemized contributions. This aligns with Duncan's pro-business platform. The full report shows total receipts of **$35,741.40** (with Duncan's own loans/self-funding via Schedule D at ~$32,800).
