From MSNBC's Adam Verdugo
Ken Duberstein, former Republican chief of staff to President Reagan, told MSNBC's Norah O'Donnell today that the pick of Palin has undermined John McCain's credibility.
"What most Americans I think realize is that you don't offer a job, let alone the vice presidency, to a person after one job interview," Duberstein said. "Even at McDonalds you're interviewed three times before you're given a job."
Duberstein joins a list of prominent Republicans to criticize McCain's running mate pick -- including former Secretaries of State Colin Powell, who endorsed Barack Obama, and Lawrence Eagleburger, who is a McCain supporter.
It was later reported that Duberstein will vote for Obama.
