Not sure why you think it will be rejected? The dems hold both houses as well as the crazy governor who is pushing all of this who says he will immediately sign it into law and begin pushing law enforcement to do what ever is passed.
I have read where some dems say it will be the end of their political career but they think its the best for Virginia and the country and how its a test case for other states. A lot don't think there is enough conservatives to ever be able to overturn this at the ballot box.
