Investigative Poll Explains Busby Loss

[...]

The “culture of corruption” message, on which the Democratic Congressional Campaign Committee based most of it’s multi-million dollar advertising budget in the district, and which was a pillar of the national Democratic message going into the Busby campaign, failed. In an open-ended question where poll participants gave reasons for their vote, less than 2% cited Republican corruption as a reason for voting for Busby (Q9). Further, while people in the district viewed Bilbray as more corrupt than Busby (Q18b), Independents in particular still view Democrats as being corrupt, and as such do not believe Democrats can solve the corruption problem in Washington (Q20a). Yet still further, the “culture of corruption” message may well have been responsible for what was very low Independent turnout and for Independents to break heavily for third-party candidates (since they think both major parties are corrupt). Thus, for Democrats, the “culture of corruption” message quite possibly did more harm than good in this district.

The report also mentions that the CC/MyDD analysis of the poll results suggests that Busby’s immigration “gaffe” (“You do not need papers for voting”) does not seem to be a significant reason for her loss.
