While I generally like the idea of this sort of tool, I do wonder to what degree having a database of politicians promises and positions could make it difficult for them to make needed compromises, or even just change their mind. It's a similar idea to how having a complete transcript of a conversation when arguing with someone can make it much more difficult to reach a resolution.
