If from ready, so that he sat down and went then reformal.ru/
But there is no possibility of finishing.
If you want to finish, then you can take WordPress, one of the ready-made themes www.wpjedi.com/social-voting-themes-for-wordpress/ or search for more.
You can take our component for this and finish any other theme github.com/casepress-studio/cpupvote
I think there are other options.

Answer 2

There is a project on Drupal. It seems to be called IdeaL
Look at the site in the list of projects. For example, these:
https://www.drupal.org/project/idea
https://www.drupal.org/project/group_mind
https://www.drupal.org/project/petitions
https://www.drupal .org/project/cucumber
Try it, read the documentation, look for similar solutions in the Python environment (especially django) and on github. Install, test the functionality and the general train of thought of the creators.
