You can find the report here. Among the interesting findings:

On average, LEOs mildly supported a requirement for photo identification. However, 29% of respondents chose “extremely supportive,” 12% “do not support at all,” and the choices of the other 60% were spread across the scale of possible responses. Two-thirds also believed that requiring such identification will make elections more secure. These views do not, however, appear to be based on concerns about ineligible voters or voter fraud, which few believe are problems in their jurisdictions. In addition, 41% believe that requiring photo IDs would depress turnout, while 56%,
almost all the rest, believe it would have no impact.
