The answer is: No.
Honestly, as a non-american citizen, I would say this question is a very particular, specific question to the locals. I had to give a deep search on internet, and as far as I can tell, no record of bias news were found involving the concord election city.
we know how lethal fakes news can be for a pure and genuine election result, but really for Concord City, I have not found biased news records, at least on the internet. It is easy to identify these kind of news, when they denigrate the image of a candidate, when news is intended to affect the image of a candidate, so that, they are reflected in the numbers (polls), and also in the results.
