So NOW, Polis wants CO to be a sanctuary State...and there is a Bill to force auto-voter registration, so ILLEGALS are automatically registered to vote.
Could you show me where you are seeing that undocumented immigrants will be registered to vote? I found this article from 4 days ago, so I think it's probably the same bill you're talking about. In it, the state's Senate majority leader is quoted as saying "This is automated, and so the checking if someone is a citizen and if they’re eligible is done behind the scenes through database matches. Nobody who is not eligible because they are not a citizen will be registered to vote."
Edit: here's a link to the full text of the bill. Perhaps you have a source that mentions where in the bill they allow undocumented people to be registered to vote?
