A poll published Sunday shows Republican challenger Dick DeVos apparently leading Democratic Gov. Jennifer Granholm.
Forty-seven percent of 632 likely voters said they would vote for the Ada businessman, 42 percent said they would vote for Granholm, right percent were undecided and three percent were counted as "other," the Detroit Free Press reported.
The poll by Des Moines, Iowa-based Selzer & Co. was conducted July 7 through Wednesday for the newspaper and Detroit television station WDIV. It had a sampling error margin of plus or minus four percentage points.
A state economy devastated by the struggles of domestic automakers General Motors Corp. and Ford Motor Co. and the bankruptcies of major auto suppliers Delphi Corp. and Tower Automotive Inc. has Michigan voters unhappy with Granholm's performance and record numbers saying the state is on the wrong track.
DeVos spokesman John Truscott said the election is too far away for the poll results to mean a lot.
Granholm campaign spokesman Chris DeWitt said voters will reject economic proposals from DeVos.
The general election is in November. Earlier polls have shown a close race.
A poll conducted in mid-June by Lansing-based EPIC-MRA had DeVos with 46 percent, Granholm with 44 percent and 10 percent undecided. That poll of 600 likely voters had a sampling error margin of plus or minus four percentage points.
