NEW YORK ( CNBC) -- Mitt Romney snatched victory from the jaws of defeat in Michigan by unveiling a pro-growth, 20% tax-cut plan and by resetting his limited-government spending cuts and entitlement reforms. In other words, he delivered an economic-growth package. It served him well. It may not have been the only factor in his victory last week, but it put him squarely in the voter zeitgeist. And it may be apocryphal on Super Tuesday in Ohio, where he has come back to dead even after being down double digits. Now, if former Senator Rick Santorum had stayed on economic message with his tax-cut plan, he would have swept Michigan. But he unnecessarily wandered off the reservation. Women serving in the military; JFK's church-and-state speech; the threat of ruling out contraception -- by veering in these directions he completely undermined his economic message. And he lost because of it.
