Basically, here's the setup.
Site A, Blog A (using Blogger)
Site B, Blog B (using Blogger)
I write post in Blog A, and then I copy and paste post into Blog B, changing a few words, names, links, images here and there.
How bad is this for SEO? I am sure it's bad, but convincing leadership of changing the setup is a tedious process. I tend to go back to post in Blog B when I have time and I rewrite Blog B post to a large extent.
All comments are appreciated.
