A week ago today, voters flipped the Obama coalition on its head and voted for Republicans in a mid-term landslide that has the potential to be a transformational election. Notice how we used the word “potential.” That’s because every new majority can go in one of two directions: it can either cement its winning coalition or it can fritter it all away. History will be the judge, but the next 12 months will give us a pretty good indication of how this will turn out. Either way, what is clear is that this was a historic defeat for Democrats. And the depth and breadth of the GOP wave was greater than most people realize.
