A voter guide website

Hello, I am trying to put together a wordpress site that will allow users to go through the various pages and learn about the stances of political candidates in various local elections. I'd like to, at the bottom of each page, provide the users a simple checkbox choice of each candidate in the race they are looking at and have the resultant inputs populate a list in a side tab that can then be emailed back to the user and/or posted on Facebook. I am happy to pay for the developer version and its extended add ons for what I consider a very worthy cause, but would like to make sure this type of functionality is available first.
Thanks for your time.
