No, that would likely require finding an API that has people's beliefs listed (oh shit, Reddit). Usually politicans post their beliefs on their website which are all independent which isn't a single place to pull information from so how does one sort that info? The best thing you can do is find an application that gives you links to politicans social media profiles. You're likely able to determine where these politicians stand by just a few tweets, but even these applications generate links and don't pull information like tweets or "beliefs" directly. My favorite app is activote because it counts down days to the nearest election. It gives you social media links to all candidates. I literally just talked about this an hour ago, weird.
