The Health Care Reform package has 4 bills currently up for consideration in the Congress. One of those bills has 1,038 pages. Does the average citizen have the time to read and comprehend all that material? NO. Part of citizenry is knowing when to allow your elected representative to make the decision. Yes, you can send him your opinion, after reading, discussing, etc., however, you are going to reach a point where you are going to have to allow your representative do the job you sent him to the legislature to accomplish.
That is why you have to establish people/newsgroups/TV news/discussion groups whom you value their opinion, whatever it takes to help you reach your opinion about the item. Remember, our form of government only allows you an opinion that you give your representative/senator and you have to be ready to support his decision and the congressional process after the vote. If you are not happy with the vote, you will get another chance to correct the situation, by working harder for your position!
