"If you're not out front defining your vision, your opponent will spend gobs of money to define it for you"

In this quote, Donna Brazile is stressing the importance of being proactive in defining one's own vision. She warns that if one does not take the lead in shaping their own vision, their challenger will make the most of the opportunity and use their resources to shape it for them. This could potentially result in a distorted or negative portrayal of one's vision, which might ultimately damage their possibilities of success. Brazile is highlighting the power of perception and the need for individuals to take control of how they are perceived by others. By being proactive and defining their own vision, individuals can ensure that their message is properly and favorably conveyed.
