In an extended interview with Middle East news network Al Jazeera, consumer advocate and repeat U.S. presidential candidate Ralph Nader suggested that President Barack Obama is not supporting the labor movement because "they have nowhere else to go" except for Democrats.

"If he doesn't stand up for those millions of workers, we might as well call him a president in a corporate prison called the White House," Nader said, likening Obama's "playing" of labor unions to the stretching of an elastic band.

But this time, Nader said, the band may be just about ready to "snap." Should that happen, it could kick-start a "popular revolt" in the U.S., he added.
