Political candidate's stances on specific issues?

Question

I believe that a large percentage of the US population are politically unaware and tend to vote on the candidate whom they 'like' the most. It would be great if public can have easy access to view each issue and each candidates stance on it.

Answer 1

Another way to gauge a politician’s stance is based on the sources of their donations.

You can get an idea of where they stand via voting from govtrack and open states APIs.
