When looking at her personality and her hatred for the Thalmor, I would expect her to be Stormcloak. However, would that be somewhat betraying to Elsweyr? I would suppose most Khajiits would support the Empire instead. But Imperials really don't seem to make a fitting friend for her at all. And she would most likely relate herself to the Nords, personality wise. Thus resulting in her sympathy for the Stormcloaks.
