These sites enable you to search for voting records of your congressional representatives on issues that matter to you.
If you want there policy platforms on environmental issues you can check Hillary and Barack official sites.
I am focusing on them because they are the Democratic front runners and, if nominated, likely to be the next U.S. President.
