It's not quite an aftermath yet, as there are a few steps to go. But the shape of the landscape is clear enough - and unsurprising. President Obama, as was easy to forsee, is well on his way to becoming one of the USA's most divisive Presidents.
That a guy who proclaimed himself to be "post-partisan" should take toxic partisanship to heights not seen since the Watergate era... is only surprising to those who wanted to be conned. To believe that the most left-wing senator in the USA, with a congress run by Nancy Pelosi, and a personal history of abdicating the initiative to his party, would be anything other than the divisive figure he has become, was always a fool's expectation.
The rise in partisanship, and rancor, may not even be a bad thing. Obama and "President" Pelosi have been uniformly excellent at exacerbating the USA's most pressing problems, and that has consequences. Dealing with those consequences will require major shifts in America, as is characteristic of Fourth Turning/ Winter generational periods. In that cold environment, clarity of choice is a virtue, and bitter battles to be expected.
In that environment, too, the destruction of 60+ vote and bi-partisan expectations for major reforms may also prove useful. What it will not be, is stabilizing.
