Fine Gael members in Maria Bailey's own constituency have voted for a review of the general election ticket in Dún Laoghaire.
Over 100 people turned out to vote in a secret ballot at the Royal Marine Hotel on Thursday.
It called on party headquarters to urgently review the Fine Gael election strategy.
Deputy Bailey was not named in the motion.
Ms Bailey's political future now looks to be in the hands of An Taoiseach Leo Varadkar.
She was demoted in July by Mr Varadkar after an internal review found she overstated the impact of injuries she suffered after falling off a swing in the Dean Hotel in Dublin.
He could now go a step further than his initial punishment, and take her off the Fine Gael ticket for the next general election.
Asked by Newstalk if she was disappointed by the vote on Thursday, Deputy Bailey said: "I'm not going to comment if that's OK.
"It's an internal matter - I don't comment on internal Fine Gael".
In July, Mr Varadkar explained: "Deputy Bailey signed an affidavit (linked to a personal injuries summons) that over-stated the impact of her injuries on her running.
"The inquiry concludes that it is unlikely that a court would conclude that she deliberately sought to mislead as other legal documents talk about her running being restricted rather than not being able to run at all.
"There have been inconsistencies in Deputy Bailey's account of events to me and the media that I cannot reconcile."
A motion of no confidence in Deputy Bailey was tabled earlier this month.
