Is the Presidential Election a "political activity"?

I wanted to book a function room at the Grassroots Club for a weekly gathering of my supporters. They reminded me politely that their regulations disallow the club to be used for political activities. I said that it will be used for my Presidential election, which is supposed to be "non-partisan" and "dignified" and should not be classified as a "political activity". They are not able to decide on this matter. As time is urgent, I have to book a hotel for the gathering.
