From the LVRJ: Uh oh. Sarah Palin flubbed on television and it almost broke Twitter.
The former Alaska governor, who ran for the vice presidency in 2008 alongside U.S. Sen. John McCain (R-Ariz.), spoke at the Values Voter Summit on Friday and made a pretty significant gaffe, mediaite.com reports.
Palin’s address aimed to expose prejudice in politics. Instead, she made herself the target of another issue — factual error.
“They scream racism just to end debate. Well, don’t retreat. You reload with truth — which I know is an endangered species at 1400 Pennsylvania Avenue anyway, truth.”  http://www.reviewjournal.com/trending/palin-s-gaffe-put-white-house-1400-pennsylvania-avenue
It's pretty clear that the writer of this article is a pathetic liberal who has an agenda.
But I have not seen this same "writer" write a story and how Obama mispronounced "Corpsman":

Or Joe Biden asking a man in a wheelchair to stand up:


Or Hillary fake grilling a steak in Iowa?
So what if Palin gets she address of the White House wrong?
What difference does it make?
