It’s probably reasonable to assume that a campaign manager’s background and expertise will seep into his campaign and inform his decisions — his worldview. In football, some coaches are known for defense, while others are known for a strong offense. Either way, their teams almost always reflect their personality. This is almost always true.

Politics is similar. A campaign headed by a visionary manager will likely never be at a loss for ideas. Conversely, a campaign headed by someone expert in skullduggery — someone who necessarily has been trained to view the world through the prism of opposition research (including the practice of digging through divorce proceedings and arrest records) — will likely produce a negative, secretive campaign.

As Maslow said, “If you only have a hammer, you tend to see every problem as a nail.”
