Even as Congress was unanimously approving a law aimed at reducing the flow of junk e-mail, members were sending out hundreds of thousands of unsolicited messages to constituents

Many members of Congress praise the new policy for allowing cheaper and more effective communications with constituents. But consumer advocacy groups say the policy may unfairly give an advantage to incumbents over challengers because it allows elected officials to use government resources to communicate with voters right up to Election Day. In addition, the consumer advocates say, sending bulk e-mail messages to constituents who have not agreed to receive it is essentially electronic junk mail, or spam.
