It's obvious, but it's more about race than Republicans will openly admit.
If Sarah Palin doesn't think she's playing the race card with her "shuck and jive" Facebook post, I'd like to know what deck her card comes from. It's clearly not a full one. Is it possible that she is so culturally unaware that she thinks this is no worse than her self-coined "Mama Grizzly" self-reference? I mean, what could she possibly have been thinking, except to play to the racist undercurrents in the populace?
Samuel Johnson was a famously blusterous talker, who let his distaste of Americans be known ("They are a race of convicts, and ought to be thankful for anything we allow them short of hanging"). But he also hated slavery, rooted for slaves to rebel, and had a special anathema for the Americans who "yelped" for freedom while promulgating slavery. AND, I might remind you, he made a famously acerbic remark about those in the "Patriot" movement of his time, citing it as the "last refuge of scoundrels." Now, keeping in mind, that the "Patriotism" of his time was a political segment among the opposition... And that Palin is in the Opposition...
I dunno, I'd just kinda like to see Sarah Palin wither in his presence. For damn sure, if Johnson were to call her a racist, she'd accuse him of playing the race card. Love to see how that one would play out.
But he'd probably have better things to do with his time, like read Powerline.
