The purpose of the Senate was to make wild change- due to the fickle will of the American people- difficult to enact. This is one of the many reasons the fillibuster is such an important legislative tool.
So while the numbers are nice to see, they don't really mean all that much (I don't think).
However, I am not opposed to electoral college reform. I think these numbers help show what we all believe the be true. That the majority of Americans share the ideals of the democratic party. And being swept out of government despite our popular majority is a damn difficult pill to swallow.
