It's surprising that Castro's performance was so bad, since he had the home state advantage. However, Beto really seemed to take benefit of the fact that the debate was held in Texas, almost getting as much search traffic as Warren and Sanders. Warren was seen as the debate winner according to Ipsos' respondents.
