At 26, Reggie Love, a former Duke University football and basketball star, became then-Sen. Barack Obama's right-hand man in 2007 during his first presidential campaign.
In his memoir, "Power Forward: My Presidential Education," Love, now 33, explained what it was like to crisscross the nation with Obama, buying his clothes, carrying his luggage, babysitting his children, and serving his meals.
Love once upset Obama after accidentally buying him the wrong trail mix before a flight from Washington, DC, to New York City.

"The senator opened the bag of trail mix I'd bought and proceeded to pick out every M&M, holding them all in his palm like pieces of candy-coated toxic waste. 'I'm not going to eat these,' he said while pushing his hand in my general direction.
'Do you want them?' he asked, wrinkling his nose. 'No thank you, sir,' I answered.
The incident resulted in what Love called "the first of what would be thousands of notes to self" about the president's pet peeves.
Here are some other things Love learned about Obama's likes and dislikes:
No gum wrapped in tiny papers; he prefers plastic-packed Dentyne Ice
Only "normal" Nicorette gum, not special flavors
No candy in trail mix
No energy bars with fruit pieces
Salads are OK, but only in emergencies (because it's difficult to eat salad in a car)
Ranch dressing or vinaigrette on salads
Sandwiches are ideal
Never mayonnaise; he hates mayonnaise
Grilled fish or chicken
No fast food
He likes to have orange juice or green tea in the morning
