A smart analysis if it was class bias that made people not like Palin:

Of all the charges of bias leveled against the news media (including anti-Catholic bias), I think class bias may be the one most worth taking seriously. Blue-collar workers, poor people living in neighborhoods journalists are gentrifying and political candidates from the wrong side of town are among the many affected by this bias. Since there is no Al Sharpton (or Bill Donohue) to organize the disaffected against this bias, it tends to go unnoticed.

But I don’t think it was a factor in the way Sarah Palin was covered. The initial reaction to her “hockey mom” persona was positive. Her candidacy failed when she couldn’t demonstrate to the public that she was qualified for the vice-presidency. It’s not the news media’s fault.
