Tea bags are meant to be tossed out. They are useful, at most, once or twice in their lifetimes. Beyond that, they lose flavor and strength, eventually becoming weak as water itself. If kept around beyond their usefulness, they become unpleasant and even unhealthy, as they start to smell and begin to mold. Or they dry up and eventually crumble. Either way, they become useless.
What's true of tea bags is also true of teabaggers. However, tea bags are tossed out when they outlive their usefulness. The same can be true of teabaggers, but only if Democrats have the political will to make it so.
