QUAKERTOWN, Pennsylvania (CNN) - In a sign of last-minute concern about a traditionally red state, the independent arm of the Republican National Committee is launching television ads in Montana.
Democrats have only won Montana twice in the last half century, but Barack Obama has been using his vast resources for an aggressive push there - an Obama spokesman says they have 19 offices and 14,000 volunteers. John McCain has no Montana campaign offices.
"It's a cheap insurance policy" said a Republican official involved with the ad buy told CNN. "We don't expect a crash there, but we may as well buy insurance in case we do."
Recent polling has suggested McCain’s edge over Obama in the state may be in single-digit territory.
By law, the so-called Independent Expenditure arm of the Republican National Committee can produce TV ads and buy air time, as long as it does not coordinate with the party.
The Republican official said they spending $300,000 dollars in the relatively inexpensive media Montana media markets.
Montana now has two Democratic senators and a Democratic governor. Obama’s campaign already has an organization in the state thanks to the Democratic primary in June, which he won.
A senior McCain aide told CNN they are relying on a "very good state party" that has a few offices around the state.
