If I have 2 overlaps between my 2 majors, am I still allowed to count non-Political Science courses toward my major requirements?

Yes. The same rules for the Standard Major apply to the Double Major. Pending DUS approval, Double Majors are also allowed to count up to 3 non-Political Science courses toward their major requirements provided those courses do not count toward the second major. (For more information about how to petition for these courses, please see Question 7.)
