“We have reported them to An Garda Siochana, they have been very pro-active on it.”
Tallyman Joe Mc Carthy is reminding people to fill their ballot out right to the end.
“If you don’t give the final preferences, it could be that your vote arrives to somebody who you didn’t want at all, and if you want that person to not have a vote, you must fill in the blanks,” he said.
“Incidentally, you most vote in sequential order – you can’t go 1, 2, 3 and then 7.”
