Sure, but, as an example, "Donald Trump will help preserve traditional American culture"--at least those parts of the culture that don't talk about whether your President should lie all the time--isn't that hard to support factually. However, whether or not traditional American culture is better than the alternative cannot reasonably be addressed by evidence within 1000-2000 words. (Within those bounds it is possible to document that cultural cohesiveness positively correlates with happiness, however.)
