Help with basic polls-viewable results

Hello, I was wondering if anyone could give some 101 advice on polls. I am in need of a polling plug in that will do a couple basic things:
1. I want to place same, or different polls on some/all posts. ALSO, I would like the up to date results to appear automatically for all end-users. In other words, viewers do no need to vote, or a click the “SEE RESULTS” button.
2. Is there a plug in that automatically places a poll into any or every new posts that my readers post? Meaning, if an end user creates a post…there is automatically a poll created on the post?
It appears that I can copy and past a short code for the poll on any post that I chose.
But this is done on the back end, by me manually. I also read I could do this by making
the short code a widget. I am guessing this simply means I am making it easier and faster by have a “template” short code in the form of a ready to go widget?
Do I have this correct?
Thank you
