Supporters of a petition drive to increase the minimum wage have less than two months to go to gather the 258,000 signatures necessary to place the question before legislators.

The proposal is to raise Michigan's minimum wage from $7.40 an hour, to $10.10 per hour. If they get enough signatures, lawmakers will have 40 days to approve it. If they do not, it will go on the statewide ballot.

Recent polling shows significant support for the increase. Business groups have said it will cost jobs and hurt the economy, and labor groups counter that it help the economy and will pull many Michigan families out of poverty.

As for the campaign, it won't be cheap, at least for opponents, according to one political consultant.

T-J Bucholz of Lambert, Edwards and Associates says if it gets on the ballot, "the negative side will have to spend eight to 12-times the money to move the needle on those numbers. A 2-and one-half to three to-one margin is tough to overcome."
