Likelihood of jobs paying for MA degrees?

Hi everyone. I am graduating with a B.A. in political science this spring. I got accepted into a pretty good Master's program also in political science on a whim- but it's an expensive school in D.C. I managed to get my tuition down to about $11k/semester using scholarships, etc. Is anyone familiar with the likelihood of non-profit, local government, or archival jobs providing tuition assistance for grad programs? I'm struggling to decide if it's worth it to take out loans to get my MA over with or if I should wait for a job to pay for it in the future. It would be pretty hard to pass up this opportunity, but I don't want to be buried in student debt. I appreciate all the input.
