The Democratic Senatorial Campaign Committee's independent expenditure arm has reserved $5.5 million in airtime for Sen. Kay Hagan, D-N.C., according to a source with knowledge of the reservation.
Hagan's re-election bid is one of the most competitive and expensive races in the country. She faces North Carolina House Speaker Thom Tillis.
The DSCC has reserved airtime in at least four other states with competitive Senate races: Alaska , Colorado, New Hampshire and Arkansas. This marks the DSCC's first airtime reservation in the Tar Heel State.
These reservations can change until shortly before the advertisement's run date.
The DSCC is spending the most funds in the more expensive Charlotte and Raleigh-Durham media markets. Those buys begin Septe. 16. Buys in the Greensboro media market do not begin until Sept. 30, and the DSCC has reserved fewer points in advertisement there.
Outside groups have already begun spending heavily in the highly contested race. Senate Majority PAC, American Crossroads and Americans for Prosperity have spent millions on the race.
The race is rated Tossup by the Rothenberg Political Report/Roll Call.
