Sarah Palin was woefully unprepared to face tough interviews in 2008. Her interviews with Perky Katie and ABC News were disasters. It was a blunder by McCain campaign to throw her out there. McCain is a hog for face time on TV. So he must have figured Sarah should never refuse any TV face time either.
But the real reason McCain lost was stark contrast with Obama.
McCain was old, pudgy, short and face disfigured by tumors.
Obama was young, thin, tall & country was eager to prove this is not a racist country.
