This is a recurring theme:
1) Leftists hear something they don't understand from Sarah Palin.
2) Leftists, smug in their condescending view that Sarah Palin is an idiot, don't bother to check facts.
3) Leftists embarrass themselves attempting to mock Palin, who is correct.
This brought great hilarity when University of Wisconsin professor Menzie Chinn did it in 2008.
Now Gwen Ifill does the same, mocking Sarah Palin for referring to 1773 at a tea party, when in fact the Boston Tea Party occurred in 1773.
Of course, it's not just Ifill. It's a whole smorgasbord of I'm-so-much-smarter-than-Sarah-Palin leftists.
It's nice to see that Ifill's PBS is dropping any pretense of fairness, though.
