1 Article, 2 Websites?

So I have multiple Blogs. Two of them kinda share the same topic. I have some big articles, with Affiliate-Links and what not, that could easily fit into Blog 2 as well. What would happen if I just copy and paste my article 1:1 from Blog 1 onto my second Blog?

Would Blog 2 get penalities from Google for dublicate content?

Should I take like 10-30 min and just rewrite it a couple of times, that it at least seems a little different? Or should i leave everything on Blog 1?

​

Thanks for any help. Couldn't find anything on Google about this.
