Ms McGuinness should comfortably retain her seat in the EU elections with the quota likely to be around 20%.
Sinn Fein's Matt Carthy is sitting on 15% with Saoirse McHugh of the Green Party at 12% ahead of Independent Luke Ming Flannagan at 10%.
Maria Walsh sits on 10% and could overtake Luke Ming early on when Mairead McGuinness has her surplice distributed.
Peter Casey polled 7% while Fianna Fail's Brendan Smith will struggle capturing just 6% of first preferences according to the exit poll.
Donegal's PBP Cyril Brennan recording a respectable 3% of first preference votes in his first outing and would hope to build on that as he also seeks to secure a council seat.
