Question: City Major electionsFollow

I am new to the role as a major so I have a question about this profession:

A friend told me that u get about 300 xp per vote u get as a major per week. Ok that sounds nice enough, but I have been major for about 1 month now and only received 1500 xp with 12 votes during this time. Is there something I have to do to close the elections or something in order to receive the xp every week? And further more is it really 300 xp per vote?

Ps. I´ve been looking for some general info about the profession as a politican but haven´t found anything so far.. can someone give me a hint where (if there is any) I can read about this?
