Replying to Need some knowledge about the great depression and FDR

Alright the school year is coming to an end and i hav completely checked out.  I have a speech in the morning and i need help, here is where i need help

I need to argue that President Roosevelts personality and charisma contributed to the end of the Great Depression more than his policy in the New Deal.

Anyone got some good points that i should make, im just fucking dying here trying to think what i should say. By the way im a junior in highschool and its for an AP US History class, but its not worth a whole lot of points and i just want to get through without embarrising myself.
