In a poll of eligible voters conducted on the eve of a mayoral election, more of those polled stated that they favored Panitch than stated that they favored any other candidate. Despite this result, another candidate, Yeung, defeated Panitch by a comfortable margin. Each of the following, if true, contributes to a resolution of the discrepancy described above EXCEPT: ['A third candidate, Mulhern, conducted a press conference on the morning of the election and withdrew from the race.', "The poll, conducted on a Monday, surveyed persons in the downtown area, and the percentage of Yeung's supporters who work downtown is lower than that of Panitch's supporters.", 'Of the poll respondents supporting Yeung, 70 percent described the election as "important" or "very important, " while 30 percent of respondents supporting Panitch did the same.', "Of Yeung's supporters, a smaller percentage were eligible to vote than the percentage of Panitch's supporters who were eligible to vote."]
