Independent expenditures (IEs) will be playing a significant role again in select House and Senate primaries leading up to the midterm election. And the Campaign Finance Institute will once again be tracking that spending through a primary tracking tool on its website. The tool shows candidate receipts and independent spending together for each race, including the aggregate amount each group is spending for and against the candidates. The IEs are updated almost daily. It is also possible to track each group’s expenditures in detail by clicking the group’s name.
