The largest problem of showing your political views in a professional environment is that it is unprofessional.
If you have the choice, avoid any correlation between politics and your work. Those sympathizing with the relevant person/ideology will be only a little bit more friendly to you. While it will be a red flag for those opposing it.
If you are sympathizing with a political view, sacrificing a little bit of your professional reputation may be a rational choice to make the world a little bit better.
It is your choice how you balance the advantages and disadvantages.
Specifically in the case of Trump:
- He is not only the current top Republican (= top bad guy of the opposition), but he is also the president of the U.S. So, make your project look like you are crawling data from various sources, with Trump only being a part of it, because he has one of the most viewed Twitter accounts. The focus should be on the crawling and twitter automatization, and not on politics.
- But there is currently a little hysteria in the U.S., it seems you have an extraordinary situation with many psychos on all sides. They can be dangerous for you. Although people tends to be more tolerant if you make clear that it is a professional work and not a political statement from you.
My personal balance is that I do political activity, with my own name, only in friendly circles. But I don't make a secret of my political views anywhere - I only don't put them in focus.
