She said the following:
I'm looking forward to meeting [Biden] too. I've never met him before. But I've been hearing about his Senate speeches since I was in, like, second grade."
Two things: when Palin was in Second Grade, Biden hadn't been elected to the Senate. And when she was in third grade, do you really believe she was hearing about speeches by Joe Biden? Who in the national press corps at the time were hearing about Biden's speeches in 1972?
