Re: “Romney would have repeated Reagan’s landslide if the nation still had the demographic mix of 1980.”
Most people are not aware that 91% of Blacks and 66% of Hispanics voted AGAINST Reagan in his 1984 landslide reelection.
And Reagan could not be elected governor of California in 2012 with those numbers - thanks to his own “Reagan Amnesty” of 1986!
