Labour leader Eamon Gilmore has said he does not believe people have lost faith in the party.
Speaking on RTÉ's Six One News, he said that the party went into Government having inherited a terrible mess but had managed to turn this around.
The party had made it clear that difficult decisions would have to be made, he said.
Mr Gilmore said the essential commitment made to voters in the last General Election was that Labour would get the country out of the bailout and would see the economy recovering again.
This is being achieved through the improvements in the economy but more needs to be done, he said.
Mr Gilmore said it has been a difficult three years but decisions had to be made that were in the best interest of the country.
Meanwhile, Fianna Fáil leader Micheál Martin has said Friday's elections will be an important yardstick for the party in terms of its recovery and renewal as a party.
Speaking on the same programme, he said it was clear on the doorsteps that the area of discretionary medical cards is a huge issue across the country.
Even people who do not have medical cards have been offended by, what he called, the lack of decency and humanity that has been reflected in the Government's policy change on this issue, he said.
Mr Martin said his party has been extremely active in developing credible alternative policies and this has been its main role in the current Dáil.
He said it had put forward a policy that there should be an independent mortgage resolution office to arbitrate between banks and their clients because banks were using a veto.
