"We have seen in elections right around the globe that people actually turn to Facebook to share with their friends the issues that will define the way that they vote leading up to polling day.
"What we've seen is actually, thus far, health has taken a slight lead in the way that people are talking about this election, until just about a week ago when the economy budged ahead."

Glad to see the issue of mental health is being given priority on #RTE2ElectionSpecial after it's been largely ignored in coverage so far— Orna Clarke (@OrnaClarke) February 21, 2016
Original story: Facebook is hosting a General Election debate at its European Headquarters in Dublin tonight.
The social network reports that Taoiseach Enda Kenny has been the most widely discussed political leader on its site of this election campaign so far.
Tonight, seven politicians will go head to had in the debate broadcast on RTE 2 from 9.30pm.
They include Health Minister Leo Varadkar, Sinn Féin's Mary Lou McDonald, Minister of State Aodhan O'Riordan, Independent Averil Power and Fianna Fáil's Timmy Dooley.
Facebook's Elizabeth Linder, says interactions and political engagement typically peaks online during a televised debate.
"At Facebook we refer to this as second-strain behaviour, so that is to say as people are watching a major event play out on television, they're sitting at home on their couch or out at a pub around the corner, reacting to and sharing information."
