Donations from individuals passed through WinRed or ActBlue are not included. Company and ticker matched by name; no ticker means no listed company was found; for other committees the sponsor as registered with the FEC. Member's trades counts every disclosed trade in that company's stock. Filers that aren't committees are combined into one line.
