Actually, Peter Davidson is a lot more polite in expressing his political views than other Doctor Who actors.
In SFX magazine, Tom Baker blasted Bush & Blair and wished Bill Clinton was President again.
Also at a DW Convenation that I attended in Chicago last November, Sly McCoy made a couple of cheap shots at American foreign policy.
McCoy: "I held a fundraiser with Ben Kingsley for Amnesty International becuase someone got to protect the world from American aggression."
well I liked his Dr Who not his politics.. most sci-fi writers and actors tend to be leftists kooks --< sigh >
