This Saturday, a tea party is planned for Kiener Plaza in St. Louis.  Organizers say they'll talk about health care reform, which has become one of the central issues for the group.Their opposition at town hall meetings this summer brought the health care debate front and center.

   But I'm told health care will only be part of the event.  It's also to commemorate the movement that a year ago didn't even exist.  The first tea parties started in February under the banner of fiscal conservatism.  And now they say they're here to be a politcal force.
