We added Congressional Districts to the built in geocoding in 7.0.9. Just download the update.
Note these are the Congressional Districts for the upcoming election, not the ones for the current members of the house.
Thanks, Dan, that sounds great! I did download the update, though, and I"m not sure where to find the Congressional District option. Shouldn't it be under Map Options?
We added them for geocoding, not for map options. Right click on your field with congressional district data and choose Geographic Role > Congressional District.
Oh, got it, thanks!
