If by political you mean administrative and country division, internal and foreign boundaries it's just like drawing a picture or image. Use a normal map (with the divisions you want) as template and over in a new layer draw the divisions you want.. I personally use GIMP (other people use Net.Paint or Inkscape. The later uses SVG format). I recommend those three programs because they are free and well maintained by their programmers and use standard formats. Being Gimp and Net.Paint are easier ones to use.

You can use already existing political divisions or create new ones. Below are useful resources besides Wikimedia Commons that its great repository.

Regards and hope I've helped you.
