As Jon Ossoff and Karen Handel prepare for their first debate tonight on WSB-TV, special interest groups opened the spigots again on Tuesday.

Republican and Democratic groups reported spending at least $1.3 million on the race Tuesday.

Gabriel Debenedetti, a national political reporter for Politico, first announced the cash dump on Twitter:

Debenedetti found that the House Majority Fund, a Democratic group, reported $250,000 and the Democratic Congressional Campaign Committee added another $600,000. On the GOP side, the Congressional Leadership Fund kicked in $115,000 and the Republican National Committee added $300,000.
