Poll Suggests Dem Senate Primary A Two-Way Race, But Many Undecided

The race for the Democratic nomination for U.S. Senate is heating up just weeks away from the start of early voting. 

Cal Cunningham's campaign announced that a new television ad will begin broadcasting in the Triangle area this week. It's part of a seven-figure investment in media buys for the Lexington Democrat.

A recent survey from Raleigh-based Public Policy Polling found it's essentially a two-way race, with Cunningham ahead of state Sen. Erica Smith. Three other candidates are in the single digits.

But the poll found more than half of voters hadn't yet decided who they'll vote for. 

The gay-rights group Equality NC endorsed Smith this week. A group called the VoteVets Action Fund has been running ads backing Cunningham.

Republican Thom Tillis is the heavy favorite to win the GOP primary.
