Key numbers to compare
>Turnout
43.9% last time.
>Winner's Votes
Michael D. Higgins won with 55.% of the vote, amounting to 822,566.

As it stands, turnout appears to be falling anywhere between 39% and 45%. Highest projected number for Connolly I've seen is 63%, but that seems very incorrect. I guess she'll be in the high 50s.
