Via Business Insider and Ace of Spades:
Consumer Metrics Institute constructs a U.S. consumption index based on actual transactions data for a range of major discretionary purchases such as cars, houses, durable goods, and vacations.
The advantage of the institute's method is that consumer transactions data might be able to indicate the direction of the economy before U.S. GDP data is officially released.
This metric of CMI's has been tracking the GDP pretty closely since 2006 and seems to lead "official" figures by 2-3 months. It just fell off a cliff. A "long hot summer" could be on the way just in time to take the impending Democrat blood bath "to the the next level".
