This is going to sound really rough. But you likely need to hear it.
A political science degree on its own does not really amount to much initially on the job market. I stress the word initially. It is a degree that builds in value with experience and more education.
Most of us use it as a bridge to professional graduate programs. Applied Statistics, Public Administration (MPA), Business Administration (MBA), Public Policy (MPP), Law (JD), etc. On its own its not worth much. Once you have the graduate degree you are generally fine and can hop between state and federal government, and government contracting jobs.
Someone threw out great advice, and that is to try to get in as a paralegal.
The question is to where do you live. Because it is pretty useless some places more than others. You need to live in a place where there is a large number of lawyers (Chicago, LA, NYC, etc), or DC. Again...paralegal work is probably best if you need a job and your admin experience is directly relevant.
The other bit of advice is you need to work on a political campaign on some point for congress as a hill staffer. It is not unusual for those who work on the campaign to be set up with jobs in DC at public interest groups
I can go on. No one is gaslighting you, you really just don't know the system of finding jobs yet and are likely in the wrong place. Also let me be blunt, early career sucks. It has sucked for the last 20+ years. There is a great deal that is just difficult to figure out and finding the right place can be hard.
I should note, ultimately I left public policy for tech jobs, and I have been working in tech for nearly 15 years.
I should note, put in your early career time, seek out paralegal work or political campaign jobs. Make it a plan for both grad school and DC. Identify government contractors as well no matter what level of government.
It can take years to really find a place career wise where you will be happy, and often a career change or two. It may not end up having anything to do with your education either.
