I suppose the Presidency of George W Bush and the actions of the Tea Party Republicans have done a lot to discredit "conservative" policies in the more diverse electorate of the modern day.
The former is certainly untrue given the latter came into being.
The Tea Party is NOT reflective of the electorate in general.
And yet somehow the GOP got a higher share of whites than it has gotten in years.
For reasons involving voter enthusiasm and effectiveness of messaging, which have in the subsequent fifteen months returned to more normal levels relative to either 2010 or 2008.
