Obama 2012 Campaign Helped By MoveOn.org, AFL-CIO Super PAC Alliance

Ten million more voters went to the polls and voted for Obama in 2008 due to the efforts of labor unions and other Democratic base groups.

When labor doesn't show up (to vote, to work phones, to walk precincts), it's because they're not buying what's being sold to them.  Their hearts aren't in it.  

I'm not impressed by this announcement that MoveOn, et al, have signed on to Obama.  That's not the rank and file.  Among rank and file union members, Obama has been a miserable disappointment.
