Love and Politics
I read somewhere a while back that Allison Janney, who played C.J. Craig on The West Wing, was once asked by a fan why there were so few love stories on the show. Janney responded quickly, arguing that most people forget one of the biggest love stories on the show, Leo and President Bartlet. It's quite true.
There are lots of other examples. Anyone, from staff to the candidate, who works long enough on a campaign falls in love with the idea of the effort--the dream. It can definitely be called romance.
