For a statewide ballot initiative targeting a November General Election (e.g., November 2028), the typical timeline spans 18 to 24 months from initial drafting to the ballot.
Late Year 1 (e.g., late 2026–early 2027). Draft initial text with legal counsel to ensure single-subject compliance, clear title drafting, and strategic policy alignment.
Open-ended start; final statutory deadline is late March of the election year. Submit draft text to the Legislative Council Staff and Office of Legislative Legal Services (OLLS). A public Review & Comment meeting is held exactly 14 days after submission. Revised drafts can be resubmitted after major changes.
First Wednesday of December in Year 1 through mid-April of the election year. File with the Secretary of State by 3:00 PM on the 12th calendar day before a scheduled Title Board meeting (held the 1st and 3rd Wednesdays of each month). The Colorado Title Board (designees of the Secretary of State, Attorney General, and Director of Legislative Legal Services) cannot set a title if the measure contains more than one subject (C.R.S. § 1-40-106.5).
Motion for Rehearing must be filed within 7 calendar days of the Title Board's initial decision; Board hears it within 48 hours of the 7-day period's expiration. If appealed to the Colorado Supreme Court, petitions are filed within 7 days under C.R.S. § 1-40-107(2). The Court resolves single-subject challenges in approximately 3–8 weeks.
Can begin immediately once title approval and petition format are finalized. Proponents have up to 6 months to circulate petitions. Submission deadline: 3 months before Election Day (the first Monday in August of the election year).
The Secretary of State has 30 calendar days to verify signatures using random sampling. If signatures fall short, proponents have a 15-day cure window to collect additional signatures under specific statutory thresholds.
September: Secretary of State certifies ballot order. October: Voter Information Analysis (Blue Book) mailed to all registered households. November: General Election Day (first Tuesday after the first Monday in November).
Mark Grueskin is widely considered the state's preeminent expert on Title Board mechanics and single-subject litigation. Clientele includes Democratic legislators, labor unions, and civic advocacy groups.
Go-to firm for progressive structural reform campaigns and ballot measures expanding democratic access. Martha Tierney has served as counsel for the Colorado Democratic Party and board chair for Common Cause.
Handles high-stakes ballot initiatives with heavy institutional backing; excels at constitutional litigation across the political spectrum. Major corporations, trade associations, and well-funded coalitions.
Useful as co-counsel to vet single-subject vulnerabilities from a conservative perspective. Suzanne Taheri previously served as Deputy Secretary of State under a Republican administration.
| Feature | Statutory Initiative | Constitutional Amendment |
|---|---|---|
| Signature Requirement | 5% of votes cast for Secretary of State in preceding general election (~124,000–126,000 signatures based on 2024 election) |
Same 5% threshold |
| Geographic Distribution | None — signatures can be gathered anywhere in the state | Must collect at least 2% of registered electors in each of Colorado's 35 state Senate districts |
| Enactment Threshold | Simple majority (50% + 1) | Supermajority (55%) — required since Prop. 71 (2016) |
| Legislative Amendment Risk | Legislature can amend or repeal with a simple majority | Legislature cannot amend without voter approval |
| Statutory Initiative | Constitutional Amendment | |
|---|---|---|
| Signature count | Same (~124K) — no threshold advantage | Same (~124K) |
| Geographic spread | None — gather signatures anywhere in the state | Must hit 2% of electors in each of 35 Senate districts — operationally harder |
| To pass | 50% + 1 vote | 55% supermajority (since Prop. 71, 2016) |
| Legislative durability | Legislature can amend or repeal with a simple majority — a future session could gut the assembly process | Legislature cannot amend without returning to voters — much harder to unwind |
The legislative-durability question is the central strategic choice: statutory is easier to get on the ballot and pass, but a hostile legislature can dismantle it. A constitutional amendment is more durable but faces a higher bar at every stage. Worth getting a direct read from legal counsel on which structure better protects the assembly process long-term.
Signature firms charge by the verified, valid signature — not by the hour. The cost per signature is set by how quickly a circulator can collect them, which is almost entirely determined by how fast a passerby can understand and want to sign the petition.
| Issue Appeal Level | Examples | Avg. Cost / Valid Sig (CO) | Typical Total Drive Cost (CO) |
|---|---|---|---|
| High — populist, visceral, fast pitch | Reproductive rights, marijuana legalization, minimum wage | $8 – $14 | $1M – $2M |
| Moderate — good-government, requires brief explanation | Ranked-choice voting, open primaries, redistricting, citizen assemblies | $15 – $22 | $2M – $3.5M |
| Low — dry, technical, niche | Specialized tax policy, administrative rule changes, obscure board structure | $25 – $35+ | $3.5M – $5M+ |
Cost ranges are industry estimates for professional paid-circulator campaigns. Actual costs vary with timing, weather, competing drives, and how well the issue pitches in your specific markets. All drive costs assume a 30–40% invalidation buffer — campaigns collect 1.3–1.7× the required threshold to guarantee qualification.
Colorado's lower raw signature count makes it meaningfully cheaper per campaign than the larger midwestern initiative states — even at the same cost-per-signature rate for political reform. Ohio is the most expensive entry point; Missouri sits in between.
| State | Signatures Required | Geographic Distribution Rule | Political Reform Cost / Sig (est.) | Total Drive Cost (est.) | Pass Threshold |
|---|---|---|---|---|---|
| Colorado | ~124K (5% of SoS vote) | Constitutional only: 2% of electors in each of 35 Senate districts | $15 – $22 | $2M – $3.5M | 50% + 1 (statutory) / 55% (constitutional) |
| Missouri | ~170–190K (8% of governor's vote across 6 of 8 congressional districts) | Must hit threshold in ≥6 of Missouri's 8 congressional districts | $18 – $28 | $3.5M – $5.5M | Simple majority |
| Ohio | ~410K (10% of governor's vote across ≥44 of 88 counties) | Must include 5% of electors from ≥44 of Ohio's 88 counties | $18 – $30+ | $6.5M – $9M+ | Simple majority |
Cost estimates for political reform initiatives; costs will be lower for high-appeal issues (see table above). Ohio and Missouri signature counts are approximations based on recent gubernatorial election totals — verify against the most recent certified election results before budgeting. Colorado's constitutional amendment distribution requirement adds field complexity that moderately raises costs vs. statutory.
