The University of New Orleans Survey Research Center (SRC) conducted a statewide telephone poll of 600 likely voters in Louisiana. Telephone numbers were selected at random from a sample frame of likely voters. A likely voter is defined as an individual who has voted at least three times in the last five statewide elections. Interviews were conducted November 2-8, 2015. The combined landline and cell phone sample matches the gender, age, and race parameters from the voter file obtained from the Louisiana Secretary of State. The margin of error is +/- 4.0 percent at a 95% level of confidence.
