@Robert Gentel,
Your premise may be true mathematically, but in terms of elections, political gains are far more important than mathematical ones.
If, for whatever reason, Democrats sat out this election, that was an undeniable gain by Republicans.
I get that people disappointed by the results of this election are attempting to find solace wherever they can, but your premise is meager solace.
As george noted, it is indisputable that Republicans have a clear advantage on all levels across the country.
Now I know that disappointed Democrats will argue it's because the Republicans have rigged the system, but that's just a crybaby response.
It may or may not be that there is a majority of US citizens who want to see progressive politicians in power, but if they don't care enough to get off their asses and vote for them, whose fault is that?
Better that our governments (at all levels) are run by the choices of citizens who actually care.
It's ironic because progressives reliably charge Republican voters with ignorance, and yet if your premise is true, Republicans are winning because Republican voters are more interested and engaged than their Democrat counterparts.
Cynical stoners, and ignorant recipients of Federal largess don't win elections.
