Actually, in many ways things haven't changed that much. For example, Romney won whites by nearly the same margin as Reagan did. But whites were 88% of voters in 1980 and now they're 72%. So in a sense Romney was like Reagan. He only ran with the wrong electorate.
And that electorate is never coming back, thankfully.
Although I don't think diversity is a bad thing...that comment was entirely in a political strategy sense.
I understand that many countries aren't as culturally diverse as the US, and that's fine. But the American way has always been to celebrate diversity, so it doesn't sit well with me when I hear Romney and Ryan insult Obama's diverse coalition of support by implying that we're all a bunch of freeloaders who want a handout, or to hear Bill O'Reilly whine about the decline of traditional America which is not so vague code for white patriarchy.
