Marco Rubio has been all over the map in Iowa. Quite literally.
The Republican presidential candidate is on a nine-day run ahead of Iowa's lead-off caucuses next Monday. His itinerary includes college towns, larger cities and rural outposts.
After months of promising that his campaign was on the verge of ramping up in early-voting states, Rubio appears to be doing just that, with just a week left until the first votes of 2016.
He dismisses the notion that he's changing in the 11th hour because he has to play catch-up. Rival Ted Cruz has dedicated significant time and resources campaigning all across the state, versus Rubio, who has focused more on Des Moines and the state's other urban areas.
