Six Republicans said they were already committed to a candidate, with three saying they were supporting Romney and three picking Illinois lawyer John Cox.

The Romney supporters cited his management skills and experience, with one respondent calling him "A solid candidate with good management experience at solving problems." That respondent also said Romney "doesn't seem to be an ultra conservative, perhaps more moderate than many others." Those who picked Cox cited his status as a D.C. outsider and his conservatism.
