Capitol Gains?

Winning the House but not the Senate would translate into winning the popular vote but not the Electoral College. Again. 

The Democratic Party cannot complain about the Senate or the Electoral College. It has always known that they were there, and it regularly used to win them.

If it can no longer win them, then it is no longer a national party. If it would no longer want to win them, then it would no longer want to be a national party. In that case, it ought to make way for something that would.
