Please see this introduction for discussion of methods and motivation underlying the Advantage Gauge.
This week, Lawrence Lessig's Mayday PAC (to end all PACs) made its very first independent campaign expenditures: $143,420 for radio ads in support of its endorsee Jim Rubens (R; NH-Sen).
These first (and latest) expenditures bring Mayday's total FEC-reported campaign spending balance, to date, to:
Pro Republicans: $143,420
Pro Democrats: $0
The Mayday Advantage Gauge is updated weekly on Thursday mornings.
