I do know Ras uses registered voters. NPR? Probably not.

This poll was likely voters, but every single listing of a question—candidate or position—had the ‘NPR’ candidate or position first, without any rotation.

Your information is incorrect. Rasmussen uses likely voters. (Of course, unregistered people shouldn’t be likely to vote, but I don’t think Rasmussen considers the ACORN effect :^I) NPR uses registered voters.
