Considering the raising interest towards ongoing presidential elections in the USA, I'd like to clarify using election, voting, and probably president and voting-systems tags. The last two, in my opinion, are not that much abused, however.
Many questions are being unadvisedly tagged with several/all of those, and this makes searching by tag pretty difficult.
Is there a plain English description of which tag should be used?
I have my own (naive) understanding of these, but I'm afraid my English wouldn't let me make a good writeup on this topic.
