Rebel Fine Gael TD Lucinda Creighton said she is not surprised by the low turnout in polling stations across the country so far today.
Speaking to Independent.ie after casting her own vote in Donnybrook this morning, Ms Creighton said the weather could put some people off voting in today's referendums on Seanad abolition and the creation of a Court of Appeal.
"I suppose I'm not surprised. I mean obviously I'd be hopeful that it would pick up during the day. At least it's not really raining in Dublin this morning so hopefully people won't be put off by weather," she said.
"Hopefully it will pick up throughout the day and there'll be a higher turnout than expected later on today."
Some rural polling stations are polling lower than 5pc.
Ms Creighton, who lost the Fine Gael party whip in July after voting against her party during the vote on the Protection of Life During Pregnancy Bill, said she is somewhat optimistic that the Seanad will be saved.
"I'm reasonably optimistic. I think it's impossible to tell. Of course a lot depends of turnout and who turns out, but that's anybody's guess to be honest. I don't know anybody on either side who are certain of an outcome.
"Recent referenda have shown that you can have a very different outcome to what the polls indicate on the lead into a referendum, so I don't think anyone can say definitively."
