This week we meet a man who loves maps, elections and naturally Eurovision. We dip our toe in the recent presidential election and find out how you can use maths to see if someone is really trying to steal an election. Not through mysterious bundles of mailed in ballots, but by packing and cracking, drawing funny looking amphibious electoral maps. 

We hear why we need to Build That Wall in Ireland. (A beautiful colourful electoral wall. So that CNN's John King can feel at home when he visits his cousins.)

But all of that is mere fluffing before the substantive issue: Why Albania loves the Eurovision. WIth Adrian Kavanagh Lecturer in Geography at National University of Ireland, Maynooth.
