WASHINGTON -- Just over a year ago, Michele Bachmann and Sarah Palin stood happily together on a stage in Minneapolis exhorting their Tea Party followers and trading "you betchas."
This week, their relationship changed. Bachmann's new strategist, Ed Rollins, harshly criticized Palin, describing her as "not serious," and what was once a natural alliance has turned into a potential rivalry.
The collision may have been inevitable. Bachmann and Palin appeal to the same stripe of the electorate and are strikingly similar in style and ideology.
