The race to replace Senator Harry Reid is tight between likely Republican and Democrat party nominees. The early poll (see the full results here), show Republicans with a slight edge, but nearly all figures are within the margin of error. The survey from Monday night shows how Democrats Dina Titus and Catherine Cortez Masto would do if paired in a general election with either Joe Heck or Mark Hutchison.
Joe Heck appears to have the most initial support from Republicans, and Dina Titus from the Democrats. Regardless of whom each party nominates, November 2016 will be a very competitive race for Senate in Nevada.
