That doesn’t follow. Even in recent history, most Presidents command large electoral vote majorities. In my life time, 7 of 10 elections ended in a more than 60-40 margin in the electoral college, including both Obama wins.
What difference does that make? It's either moving the goal posts so your team can win if they're out of power or it's entrenching your team's position if they have power. Either way is an outrage to someone, and so any reform comes at the wrong time.
I took the OP’s argument to mean that, even if you can get a consensus that the electoral college should be changed, people should hesitate to do so where close races mean that the change will be outcome determinative for particular races. My point is that we still routinely have candidates winning massive electoral college majorities. If people otherwise were in agreement that a change was warranted (note that more than 50% of republicans supported abolishing the electoral college as recently as 2012), there are still opportunities to change the system where it won’t change the result of the current election.
I really don't see the point you're making.
