on november 27, 2006, proposal 2 was certified officially by the michigan secretary of state to have passed by a margin of 58% to 42% (2,141,010 "yes" votes to 1,555,691 "no" votes). the last reported poll of october 15, by the detroit news, showed mcri to have up to a 50–41% lead. in another free press—local 4 michigan poll conducted by selzer & co. inc. of des moines between october 8 to october 11 of 643 likely voters, it was shown that 41% were in favor of the mcri, while 44% opposed the measure, and 15% of the voter poll were undecided. the poll had a margin of error of 3.9% making the poll a statistical dead-heat. another poll, from mid-september 2006, showed mcri was up 48–37 with 15% undecided, with the pollster admitting that his previous polls had not used the exact language of the proposal until the sept. poll. the entire polling process highlighted an ongoing debate about the scientific value of modern phone polling on questions of race or controversial social issues where the polled members of the public may be "embarrassed" by social desirability bias to give a truthful response about their intended vote for fear that they will be identified. the effect, which was predicted by several michigan political consultants and even some pollsters themselves, represents a new concern in polling accuracy.
