Republican classic conservatives turning on McCain

The list of intellectual republicans either officially endorsing Barack Obama, or expressing criticism of the McCain campaign keeps growing.

Last week we saw two prominent media conservatives endorse Senator Obama: Michael Smerconish, a radio talk show host, and the novelist Christopher Buckley. Buckley is the son of William Buckley, one of the key founders of the modern conservative movement.

Many of them, like Colen Powell, have cited concerns over McCains choice of Sarah Palin for a running mate.

Peggy Noonan, a former speechwriter for Ronald Reagan, was the first of several conservative pundits to say publicly that she felt betrayed by the choice of Sarah Palin.

Kathleen Parker, another National Review columnist, wrote that Mrs Palin was "clearly out of her league" and should step down as the vice-presidential candidate.

George Will, another influential conservative writer, raised questions about whether Mrs. Palin is qualified to be president and compared the "Palin bubble" to the dotcom and housing bubbles.

David Brooks said Sarah Palin "Represents A Fatal Cancer To The Republican Party" and said she is "absolutely not" ready to be president or vice president.

Lifelong conservative Republican Ken Adelman says he will vote for Obama, adding "Not only is Sarah Palin not close to being acceptable in high office—I would not have hired her for even a mid-level post in the arms-control agency."

Can we point to any prominent democrats endorsing McCain/Palin? What does that tell us?
