The article does mention it.
What proponents of the National Popular Vote don't tell you is that the compact is not necessary.
Any state can pass a law now to award their Electoral College vote to the winner of the national popular vote on its own. Why will no state step up and unilaterally do this to be a leader for the cause?
Why are they hiding behind this need to have a compact of 270 votes lined up before making the change? Why won't some liberal state lead by example, take that first step, and just do it now?
