The ADP report is based on data from about 340,000 businesses employing more than 21 million workers. It is supposed to be independent and fairly accurate.
IMHO, some of this has gotta be the Mississippi flooding and the terrible tornados in the south and midsection of the country. And some of it may also be the inability of our elected leaders to work together on the debt/deficit and to get the economy growing and creating more jobs. Consumer confidence took a big hit in May, as did housing prices. None of this bodes well for the future, short, medium, or long term.
