O'Reilly was right and wrong when he said that "the white establishment is now the minority". its not that the white establishment is the minority but rather the white uneducated right wing white man is the minority.
Republican can rile their base all they want with hate messages or code words, the'll never win major elections because the way they campaign turn offs progressive and minority voters.
Asian, Black and Hispanic population will grow. Young voters will be even more progressive in a few years. SO the Doom and Gloom for the republicans is real.
