I'd like to recommend an important resource I just discovered to my fellow Catholic citizens of the United States:
the Catholic Advocate Congressional Scorecard.
With this handy tool you can keep track of how your Senators and Representatives in Congress--especially the Catholic ones--vote on the crucial life and marriage issues as well as other issues of importance to Catholic voters. (For example, you can find out how your Senators and Representatives voted yesterday on the Respect for Rights of Conscience Act.)
Take a look!
