<human>: Can you give me the gist of the text in a nutshell?

I am currently about 8 weeks in to a Civil Engineering internship. I would really like to go to the Democratic National Convention to march/protest. This is a cause I'm really passionate about and is not the point of this post. I just want to make clear the date is non-negotiable. 

In my internship, I don't get any paid leave. Pretty standard for a US internship. I'm not sure if I am able to get unpaid leave without making up the hours. Since I would not be able to make it back Tuesday, I'll be unable to make 40 hours in 3 days. Should I ask for the time off? If I don't get it, would it hurt my future badly to quit early? I've got a few co-workers that would give me good references as I am now, but I am worried that quitting early would have a negative impact on that. I'm not planning to work on this firm again next year, so that doesn't have a large impact on my decision. Sorry for the rambling, I'm just really worried about my future.
<bot>: I want to go to the Democratic National Convention. I have no paid leave. Should I ask for unpaid? If not, is 10 weeks too short for an internship?
