The institution of traditional marriage can be protected through actions taken in the arenas of Public Education, Legal Policy, State Policy and Federal Policy.
In the States
It should be kept in mind that, while the marriage debate is now a national issue, it is not primarily a federal policy matter. By tradition, and in accord with our constitutional division of power between the federal government and the states, marriage is recognized and regulated by state law. Most of the key battles, therefore, will occur at the state level.
In addition to the legislative measures, citizens of many states have successfully organized petition drives to place an amendment to preserve marriage on their ballot. For information on the success of the ballot initiatives as well current progress in each state, click the link below.

In addition to the legislative measures, during 2004 citizens in six states organized petition drives to place an amendment to preserve marriage on their ballot. There was a total of 13 states that passed a constitutional amendment to preserve marriage during 2004. Click here for more information.
On the National Level
Congress has already considered a marriage protection amendment. The Senate defeated a procedural motion about the measure by a vote of 50 to 48. (two Senators did not vote.) It did not pass in the U.S. House of Representatives either. It gained 227 Yea's and 186 Nay's. 20 U.S. Representatives did not vote.
Under the leadership of Senator Frist, the Senate will vote on the Amendment a second time in June of 2006.
