It looks like NCLR and seven other allied groups are learning a lesson from NumbersUSA. If you monitor the votes and positions of members of Congress, grade them and make them available to your supporters, you can more easily hold politicians accountable. It's helped to make the tiny minority of anti-immigration voters represented by NumbersUSA seem a lot larger over the years. And even pro-immigration advocates (myself included) use the NumbersUSA ratings to get a quick read on the voting history of particular members of Congress. I just use the ratings in reverse. The better the NumbersUSA grade, the worse I regard the person's voting record.
NCLR is warning that it will publish its grades and politicians will have to face the music with Latino voters, Roll Call reports. The grades will be published ahead of the 2014 elections and distributed to Latino voters around the country.
