Midlands North West MEP Matt Carthy believes Sinn FÃ©in will recreate history at the next general election by returning a Longford/Westmeath TD.
The pledge was delivered by the father of four during a visit to the county last week.
The Monaghan native visited a number of locations in Co Longford including Longford Womenâ€™s Link.
Mr Carthy said the impressive performance of candidates in the recent local elections, despite not taking a seat, and that of a growing public apathy only strengthened that claim.
â€œThereâ€™s no question in my mind that there will be a Sinn FÃ©in TD for Longford-Westmeath,â€ he said, shortly after popping into Longford Womenâ€™s Link for a visit.
â€œFianna FÃ¡il let the people of this constituency down and now Fine Gael are doing the same with cuts to spending and removal of services to communities, a lack of investment and infrastructural measures. People have had enough,â€ he said.
Mr Carthy, who successfully claimed one of the Midlands North West constituencyâ€™s four seats last May, refused to name any parties Sinn FÃ©in would go into coalition with.
What he seemed more keen on getting across was the promise his presence in counties like Longford was not merely geared towards attracting votes.
â€œIt was one of the criticisms we (Sinn FÃ©in) made against previous MEPs and itâ€™s a charge we donâ€™t want levelled against us,â€ he said.
That level of presence at a local level was an area, Mr Carthyâ€™s fellow Sinn FÃ©in and Athlone Town Cllr, Paul Hogan was quick to allude to.
He said over the past two weeks alone, the party received 23 new membership applications from Longford addresses, adding to the three cumanns that had recently come on stream countywide.
One of those was set up in north Longford in August, on the back of the partyâ€™s impressive showing in the last local elections.
