McCain has opened a couple more state offices and that number now numbers about 14 (California just opened its first office last week)
Obama is taking Iowa very seriously and has already opened 15 offices in the state:
Obama leaps to early Iowa start; McCain slowly digs in
http://www.desmoinesregister.com/apps/pbcs.dll/article?AID=/20080714/NEWS09/807140319Democratic presidential candidate Barack Obama is off to a more aggressive campaign in Iowa than John McCain, despite the Republican having clinched the nomination three months earlier than his rival.
Obama has 15 campaign offices open and staffed in Iowa, while McCain is still plotting where to locate about half as many.
Though Obama campaign officials declined to disclose their hiring plans, they said its safe to say their 2-to-1 edge in local headquarters is a sign Obama's staff will outnumber McCain's team, which could reach 20 by this fall.
McCain's recent hiring of a state director and opening of a Des Moines-area headquarters last week soothed county GOP leaders who had worried that McCain waited too long.
But Obama's organizational advantage - in part the product of his winning caucus campaign - and the Democrats' favorable voter registration trend has some national observers taking Iowa off the list of toss-up states.
"It's in the realm of possibility that McCain could pull an upset in Iowa, but it's unlikely," said Larry Sabato, director of University of Virginia's Center for Politics. "Obama has had strength in Iowa from the beginning, which we saw on January 3. And McCain, Iowa's just not his state." Iowa is among 18 states listed as top targets by both campaigns in the effort to cross the 270 electoral-vote threshold required to win.
In 2004 Bush took Iowa by 10,000 votes.
