When I say "we" I mean about 1/3 of us who voted for this, and about 1/3 who decided that either way was good for them. That includes a bunch of people who are diametrically opposed but for whom the main alternative wasn't quite good enough.
That's roughly two-thirds of us. Those of us who took even the trivial effort to oppose this are a distinct minority.
I don't think there's any that minority could have done differently. We are merely complicit in the suicide pact that is the Constitution, whereby we go with the majority and hope the majority would let us try again in a few years. That's an increasingly dubious proposition, and now we have to decide if this social contract hasn't already been broken.
