Literally as soon as last night's second segment aired, people were asking after the chart Rachel showed comparing legislator NRA ratings with constituent polling on background checks for gun purchases. Last night was actually a bit of a scoop for TRMS on that item and I couldn't find any public links to share after the show. Now that it has appeared in several newspapers, I also find the direct links.
Just to recap: Mayors Against Illegal Guns did a heap of local polling --21 statewide polls, 41 congressional districts -- to gauge attitudes about gun issues like background checks. Then they looked up the NRA ratings for senators and representatives in the congressional districts they polled. (It takes a membership to see the NRA grades but the New York Times recently published them in a map.) The poll results show overwhelming support for background checks for gun purchases, but the NRA opposes background checks. So the idea is that if a member of Congress has a good NRA grade, their stance is more aligned with the NRA than their own constituents.
The full set of results is available as a pdf and was meant for use as a full-page newspaper ad. If you were hoping for a more shareable image file, they have this tiny-but-still-readable jpg version. They've also got all of the results broken down by the states and districts they polled.
