Taoiseach Enda Kenny described her remarks as a "disgrace" after Ms Daly said there was "almost unprecedented slobbering" over the US president and his family.
But today Ms Daly said she was "inundated" by people from both Ireland and the US who supported her stance.
Tourism Minister Michael Ring said he was "very disappointed to hear her comments".
"There were 105,000 people employed in the tourist industry here. The country had been beamed all over the world, we would never have the budget for this type of boost," he said.
The astonishing row broke out in the Dail yesterday after the Dublin North TD described Barack Obama as a "war criminal" who had increased the use of drones by 200pc, resulting in thousands of deaths.
A stunned Mr Kenny hit back: "I think your comments are disgraceful. I think they do down the pride of Irish people all over the world who are more than happy to see this island being host to the G8."
