DailyKos has an interesting poll on whether Americans believe that Africa and America were one part of the same continent. I have to say I would have said yes, but not too confidently. But what's interesting to me is that Republicans were far less likely to believe this than Democrats or Independents. The more polls I look at the more it seems to me that the large cohorts of Independents now resemble Democrats on policy more than they resemble Republicans. The cultural and political marginalization of the GOP continues. And so much money - Fox, etc. - is bound up in keeping it that way.
