He got over 130,000 votes following the 17th count - becoming the second candidate to reach the quota after Fine Gael's Sean Kelly on Tuesday.
Independent Mick Wallace is expected to take the third seat.
Fine Gael's Deirdre Clune, Sinn Féin's Liadh Ni Riada and the Green Party's Grace O'Sullivan appear to be in a battle for the remaining two seats.

Me Kelleher gave this reaction after his election.
He said: "Elated, honoured, humbled - it's democracy in action, isn't it.
"It's a wonderful feeling to be selected by your peers, by your citizens, the neighbours you know, the neighbours you don't know.
"People from across the constituency that you've never met - so it's a really humbling experience being quite truthful, and an emotional one".
Counting has concluded in the Midlands North West European constituency.
Fine Gael's Mairead McGuinness was the first to be elected, topping the poll on the first count.
