Campaign Money; Compare and Contrast

This Everytown graphic from the latest Brady money beg:



From the NY Post:

Pro-gun-control Illinois Republican Bob Dold received $3.7 million in contributions and ads for his winning bid in 2014 — after Dold cost Bloomberg $2 million for losing the same race in 2012.
Bloomberg poured $1.7 million and $3.5 million into campaign funds and TV ads for gun-control Govs. Dannel Malloy (D-Conn.) and Rick Snyder (R-Mich.), respectively, in 2014.
And Virginia Democrat Jeremy McPike should add Bloomberg to his Christmas card list after accepting $1.4 million for his 2015 state Senate race.

and he dropped $2.2million into a PRIMARY to buy Robyn Kelly her IL-2 seat.

So which corporate lobby is buying Congress?
