In an interview that aired Friday morning, Republican presidential nominee Mitt Romney told "Good Morning America" that the definition of middle income in America is "$200,000 to $250,000 or less." Romney's answer is a bit confusing, because 200,000 is included in the universe of numbers less than 250,000. If you take the statement at face value, however, it appears that Romney is using the same upper limit as President Barack Obama when it comes to middle-income earners. Obama's proposed tax hike for the richest Americans begins with taxable income over $250,000.
