David Wasserman, undisputed popular votemeister, has just updated his national House popular vote number with the certification of final results from New York State. And the Democrats now has a non-trivial lead of 1.362 million votes
. 49.15% to 48.03%.
That's not only a measure of effective gerrymandering. There's also the concentration of Democratic votes in large urban districts. And the simple fact that, like in the presidential race, different areas are contested in very uneven ways.
With all that said, though, significantly more people voted for Democratic representatives than Republican ones.
