Palin Power

Sarah is a superstar.

Thursday's highly anticipated face-off between Alaska governor Sarah Palin and Delaware senator Joe Biden was the most-watched vp debate of all time.

Last night's event was seen by nearly 70 million viewers, according to Nielsen Media Research.

That's the most-viewed debate -- presidential or vp -- since at least the second round between Bill Clinton, Ross Perot and George Bush in 1992.

Thursday's debate was...

-- 33% higher than Friday's top-of-the-ticket debate between John McCain and Barack Obama (52.4 million).

-- 61% higher than the 2004 vp debate between Dick Cheney and John Edwards (43.6 million).

-- 23% higher than the 1984 match up between George Bush and Geraldine Ferrarro (56.7 million), the former title-holder for the most-watched vp debate.
