Republican presidential candidate and former Massachusetts Gov. Mitt Romney is passed a portrait of himself to sign as he campaigns in Apopka, Fla. on Saturday, Oct. 6, 2012.

WASHINGTON — It can be something as small as positioning the candidate at just the right camera angle or as big as catching the opponent in a campaign-altering slip of the tongue.

Every day, the ground troops of Team Obama and Team Romney set out in pursuit of a common goal: winning the day. Moment by moment, hour by hour, they scramble, maneuver and hustle to gain an inch here, a foot there on the opposition.

Driving it all is the belief that by stringing together enough small, daily victories, they can help their candidate win the one day that truly matters — Nov. 6, Election Day.

There's always the next day — until time runs out to push the reset button.
