This question already has an answer here:
What is the reason behind not letting people vote again on the same post (for example -- after changing mind, i.e. downvote after previous upvote, upon further reading or after certain comments)? What this suppose to do, what prevent or in what this should help?
I can't vote again on post, where I have already voted, but I can... edit this post, do some really tiny change and then I can vote again, without any restrictions. Where's the logic?
EDIT: Neither given answer nor linked question (which most of you takes incorrectly as dupe) answers my question. I'm not talking about poor edits etc. I'm precisely asking, why I (with 2k+ rep) am blocked with this restriction, which I can very easily override by doing simple edit? In this case, 2k+ users shouldn't have this dual-voting restriction at all. This question has nothing to do with poor edits or tactical voting. It addresses this -- voting again after changing mind, after explanation by post author made in comments.
