Both Reagan and FDR projected an undeniable sense of optimism to the weary, beat down population through their vision for America delivered in in eloquent speeches marked by home-spun character and wit. And not to make too much of it, but they both beamed confidence and enthusiasm with their magnetic smiles. Honest, comfortable smiles that filled up a room. If you want to get people to follow you, the most important thing to wear is a smile. No one wants to throw their support behind a mope or a grump or someone who seems insincere or unconfident.
And for comparison.. These smiles don't convey quite the same sense of confidence and optimism.
