They call this "social voting." Basically, it's a way for you to seek advice from advisors you trust and share your voting choices with only the people you choose.
To get started, enter your zip code in the box on the top right corner of the home screen. You will be redirected to a page that includes all of the national and state-wide races you will vote on in November. On this page you can choose which candidates you will vote for, as well as how you will vote on the various policy proposals.
To add "advisors," which are organizations who endorse particular candidates, just click on the gray faces above the ballot. You can choose up to 10 advisors.
When you are finished choosing your advisors, your ballot page will look something like this: (please note, the organizations below were chosen at random and do not reflect political views of WHSV or any employee of WHSV)
When you are finished with your ballot, you can choose to share it with your Facebook friends, but you don't have to share it with all of them. The cool thing about this website is that it lets you choose who sees your information.
