I have been practicing my English reading skill for a while. I try to read news article from various sources. Lately, I found this article (link: https://www.theatlantic.com/politics/archive/2011/10/stop-forcing-journalists-to-conceal-their-views-from-the-public/247571/) and I could not understand a specific sentence. That sentence is
Were I an opportunist, I'd be salivating at the recent news from NPR, which is now on record with the precedent that it is unacceptable for the host of an opera show to participate in Occupy Wall Street.
I haven't seen this kind of structure before. It will be helpful if someone can explain me this sentence to give me better understanding.
Thank you very much!
