This is a great idea, buuuut the issue is bias sneaking in...meaning that the American public should know everything that is public about the politician...there position, there votes on what issue, there attendance and factual information. With the age we live in though where mainstream for profit media and so much divisiveness among Americans it would be a quagmire. If you do start something let me know, I could lend some time to help...good luck
Once the platform says something bad about side X, side X declares it to be a pro-Y biased platform and this attracts pro-Y people and thats basically the end.
