Dark money spending is down, but undisclosed funds are making their way into super PACs. Only 30 percent of outside spending in 2020 has come from groups that fully disclose their donors, an all-time low.
These big money groups are typically funded by ultra-wealthy individuals. The top 10 donors combined to give $642 million to federal committees so far this cycle. Roughly 98 percent of that money went to outside groups.
