BOSTON -- Former Clinton Cabinet member Robert Reich has decided to endorse Barack Obama -- and not Hillary Rodham Clinton -- in the battle for the Democratic presidential nomination.

In a blog post Friday, the former labor secretary said that "although Hillary Clinton has offered solid and sensible policy proposals, Obama's strike me as even more so."

Reich says the Illinois senator's plans for reforming Social Security and health care have a better chance of succeeding, and his approach to the nation's housing crisis and financial market failures "are sounder than hers."

Reich is a longtime friend of the Clintons.

Obama also was endorsed Friday by former Sens. Sam Nunn of Georgia and David Boren of Oklahoma.
