Colorado’s 4th District

About these numbers

• Outside spending is money groups spent on their own ads, mail and canvassing for or against a candidate. Groups can’t coordinate it with campaigns, and it isn’t counted in what campaigns raised or spent.
• Every group that reported independent spending to the FEC is listed, not only the groups on our issue pages. Groups tracked on an issue page carry a tag linking to it.
• Primary, special or general comes from the election the group listed on each expenditure. Seats with a special election this cycle show that money separately.
• Late reports are 24- and 48-hour filings made since a group’s last regular report. Earlier ones are already counted on that report, so we don’t count them twice.
• Some nonprofits don’t have to name their donors, so this shows who spent the money, not always who gave it.
