Greene, an associate professor of political science at North Carolina State University, studies elections and voting behavior, including partisanship and public opinion. Greene has published extensively in the field, and has been featured on CBS' The Early Show, NPR's All Things Considered, and in print media outlets including USA Today, and The Times (UK).
Greene says that this is "shaping up to be a good Democratic year," which means that states which were previously assumed to vote Republican - such as North Carolina - will likely be in play for Obama.
