Romney Compaign: Why Poll When You Have Internet Gamblers?

Percentage chance of winning the Feb. 28, 2012 Michigan Republican primary according to gamblers at Intrade.

According Gary Wolfram at the Romney Campaign, the internet gambling site Intrade can give you a better feeling for the Michigan primary than polls of actual Michigan Republican voters. Since “InTrade’s value as a prediction engine vs. scientific polling is debatable“, let’s look at both.

Romney was initially the heavy favorite to carry his “home state” of Michigan, but now betters at Intrade are not so sure. They now consider the state to be a toss-up.

Meanwhile, Nate Silver has studied the polling data for Michigan and gives Santorum at 76% chance of winning. Over the last two weeks, all polls have shown Senator Santorum to be in the lead.

Either way Romney has his work cut out for him in Michigan.
