The latest survey data from Rasmussen shows Sen. Kay Hagan with 48 percent of the vote, and House Speaker Thom Tillis with 46 percent.

Rasmussen has also moved the race from “Lean Democrat” to “Toss-Up.”

This is the first survey of the race to include “leaners,” those who initially are undecided or prefer a third-party candidate and are asked again to pick between the Republican and the Democrat.

North Carolina now moves from Leans Democrat back to a Toss-Up in the Rasmussen Reports 2014 Senate Balance of Power rankings. Republicans need a net gain of six seats to take control of the Senate, and they’ve long counted on North Carolina to be one of those pickups.

Among the 85% of Tar Heel voters who say they are definitely going to vote in this election, the race is a tie at 48% apiece. But just 67% say they are certain at this point who they will vote for. Among those who are certain of their vote, Tillis leads 57% to 43%, but among those who could still change their minds, Hagan has a better than two-to-one lead – 56% to 25%.
