These maps show a simple stat that's pretty striking. This one shows the widespread contributions from the NRA's political action committee to the campaigns of members of Congress since Jan. 1, 2009. A whopping $1,453,637:
And this one shows the amount of contributions from the Brady Campaign (a group working to prevent gun violence) to those same members of Congress over that same time period. It's just a little different at only $5,868:
In short: the NRA has spent almost 250 times what the Brady Campaign has on contributions to members of Congress. That's ridiculous.
