In the four weeks between Thanksgiving and Christmas, Mrs. Clinton, whose campaign has been on the defensive lately because of her own missteps and increasingly aggressive attacks from her rivals, is moving to double or triple the amount of time she has spent here in recent months. Seldom will a day go by, aides said, when either she or former President Bill Clinton will not be on some patch of Iowa soil trying to solidify her support and win over an unusually high number of uncommitted voters.
“We’re going to begin using all the assets we have,” said Tom Vilsack, a former governor of Iowa who serves as co-chairman of the Clinton campaign. “We haven’t been bashful about asking for the moon here.”
The intense attention is the latest indication of the Clinton campaign’s worry about establishing dominance in Iowa — the opening contest in the race for the Democratic presidential nomination — to match the strength she has shown in national polls. Senator Barack Obama of Illinois and former Senator John Edwards of North Carolina have waged spirited campaigns here, taking advantage of what polls suggest is unease with Mrs. Clinton among many voters.

And when Mrs. Clinton returns Monday to Iowa, aides said, she will begin concentrating on smaller audiences and intimate sessions with voters in outlying areas of the state. One stop on the itinerary, for example, is Tama, population 2,700.
“At the beginning, she didn’t understand the whole notion of relationship building,” said Mr. Vilsack, the former Iowa governor, who often travels the state with Mrs. Clinton and introduces her to voters. “She now gets it. She now understands the psyche of this process.”
