Here we go again. In the never-ending quest to identify key demographic groups that might tip an election, "Wal Mart Moms" are getting some media love heading into the 2012 election.

The Des Moines Register says that the Wal Mart moms are women who mostly voted for Obama in 2008 but went overwhelmingly Republican in 2010. But, their loyalties are up for grabs in 2012.

These women seemed to be craving change, and they haven’t seen enough of it from Obama. Herman Cain was named most often as a favored GOP candidate. A couple mentioned Michele Bachmann, but said they’d decided she was too “extreme.” One Obama supporter confessed a fascination with Ron Paul.

All of the women were disgusted with Congress, which they described as dysfunctional, childish, ineffective, overpaid. Most said they thought the next president would be more effective with a Congress controlled by his or her own party — but they were leery of voting a straight ticket. One GOP-leaning woman said the politicians should set aside their party labels and work for solutions.

The candidate who will win over Walmart moms needs to demonstrate genuine understanding for their plight, not just lip service, and reignite their hope that something can be done. Otherwise, these ladies are ready to see them on the clearance rack.

This need to put voters into easily identifiable and stereotypical blocks reminds me of a Monty Python song:
