The FEC shows reports for 13 of the 18 candidates in the GA-6 special election for the period ending March 29, 2017. Approximately $9.63 million was donated by individuals to those campaigns and another $3 million kicked in by the candidates, though $1.92 million was by Dan Moody alone. PACs added an additional $190,522, with almost all of that going to Jon Ossoff, Judson Hill, and Karen Handel. $9.44 million was spent by the campaigns through March 29.
The PDF below shows the information that was available as of last night. I have highlighted the highest in each column, excepting the Other category, with red for Republicans and blue for Democrats.
