Labor comes home, and brings an election with them...

According to internal AFL-CIO surveys, union voters supported Democrats 74% of the time, up from 68% in 2002. They focused on -- and managed to turn out -- hundreds of thousands of drop-off voters.

More than 205,000 union members volunteered for the AFL-CIO’s political program this year. Union members knocked on more than 8.25 million doors, made 30 million phone calls and passed out more than 14 million leaflets at workplaces and in neighborhoods. The AFL-CIO’s program sent out more than 20 million pieces of mail to union households, not including those sent by affiliate unions
The AFL-CIO’s “Final Four” program in the final four days of the election proved to be a powerful counter to the RNC’s 72-hour program. The AFL-CIO turned out 187,000 volunteers, made nearly 8 million phone calls and knocked on 3.5 million doors in the final four days.

Can anybody think of any other identifiable demographic beside African-Americans that turned out 74% for Democrats?

I know we're supposed to be in an era of way-new politics and everything, but it's as true today as it's been since the New Deal coalition was forged by your grandparents - when you're shopping for Democratic victory, look for the union label.
