The blurb at the top says "Republicans in Virginia", but the article body only mentions it was signed by a Republican governor. I think those blurbs are often added by someone other than the author, and that someone probably over extrapolated from the governor of Virginia being a Republican.
This would be a "man bites dog is news" thing; The pretense is that of course Democrats were in favor, but this time even a few Republicans relented and joined the vote.

So, really not sure how the author got to "Republicans in Virginia"
