Sarah Palin wisely warned Tea Party activists to keep working hard right up until Election Day — and not to “party like it’s 1773″ yet. Intellectually superior leftists from Daily Kos founder Markos Moulitsas to PBS “moderator”/Obama cheerleader Gwen Ifill took to Twitter to snicker about Palin’s historical illiteracy. But it’s the Palin-bashers who humiliated themselves, “Ummm” yourself, nitwit. Of course they wouldn’t know when the Tea Party occurred. They’re too busy wallowing in teabagging jokes and hate smears.
