Super PAC plans $8M in ads to help N. Carolina Sen. Burr

With a goal of keeping the chamber in GOP hands, the Senate Leadership Fund said it is reserving ad time starting Sept. 13 in nearly all of the state's TV markets and will air the ads regularly into late October.

Burr and other North Carolina Republican candidates are campaigning in turbulent currents with Donald Trump at the top of the ticket and GOP Gov. Pat McCrory taking sharp criticism for signing a bill limiting anti-discrimination rules for LGBT people.

While not releasing details of ad content, the Senate Leadership Fund sounds ready to go on the attack against Ross, who spent years as a lobbyist for the state chapter of the American Civil Liberties Union.
