Graduate 1 year early or graduate 1 semester early with a double major

I’m currently on track to graduate 1 year early with a bachelor in finance if I take just 1 extra class over a break. If I decide to double major with the 2nd degree in economics I would have to take 9 extra credits which are 6 credits short of a full semester. By the way, I would like to work in politics. And I’m still debating whether or not I should go to graduate school before that.
