From the New York Times:
A growing number of voters have concluded that Senator John McCain’s running mate, Gov. Sarah Palin of Alaska, is not qualified to be vice president, weighing down the Republican ticket in the last days of the campaign, according to the latest New York Times/CBS News poll.
All told, 59 percent of voters surveyed said that Ms. Palin was not prepared for the job, up 9 percentage points since the beginning of the month. Nearly a third of voters polled said that the vice-presidential selection would be a major factor influencing their vote for president, and those voters broadly favored Senator Barack Obama.
