Why can't Palin and Bachmann just admit when they've made a mistake about our history!?

Bachmann said John Quincy Adams was one of our founding fathers. He was the SON of founding father John Adams. She said the founding fathers "worked tirelessly to abolish slavery." But Thomas Jefferson maintained 600 slaves. James Madison had 106. George Washington had 306. They didn't work to abolish slavery. The announcer tried to tell her this and give he a way out. But no. Ego I guess wouldn't allow it, so she tried to be right, just like Palin on the Paul Revere gaffe c0ns here STILL want to find a way to make her right on. Sorry, when he rode through the town, which is what she was focused on in the statement, he was NOT warning the British that THEY were coming, ok? Do these women just have a problem saying, "I stand corrected. I made a mistake"? And if so, why do you think that is? Your thoughts.
