They had to invent Sarah Palin's supposedly most embarrassing gaffe when she was the vice-presidential nominiee in 2008. She never said, "I can see Russia from my house!" Comedienne Tina Fey did. As noted at NewsBusters several days ago, that hasn't altered the folklore.
You don't have to invent gaffes for Joe Biden, the man who became Vice President after the 2008 election. He generates them continually. The lists seen here and here contain many of the golden oldies through August of 2012. There have been plenty since then. His latest, following the jump, is a doozy. The smart money would be on the establishment press ignoring it, as they have the vast majority of the others.
The gaffe (beginning at the 0:09 mark):
There’s no reason the nation of Africa cannot and should not join the ranks of the world’s most prosperous nations in the near term, in the decades ahead. There is simply no reason.
Both a summit-related story at the Associated Press solely about Biden and a more comprehensive piece at the New York Times don't mention the gaffe. If a Republican or conservative vice president had said something similar, the gaffe would be the headline.
