Preston Manning has provided two highly...original reasons to not vote for Stephane Dion.
Reason Number 1: "Whereas Mr. Harper grew up in an accountant's household, Mr. Dion grew up in an academic's household."
Reason Number 2: "Whereas Mr. Harper studied economics at university (writing his master's thesis on monetary policy), Mr. Dion's degrees are in political science and sociology - adequate preparation for salon politics but not for economic crises."
So there you go. Vote accordingly.
Epilogue: It's just a little sad to see Mr. Manning - someone I used to have a great deal of respect for - belittling people who take liberal arts degrees in university in order to make a very, very weak argument. But oh well.
