TD Mary Lou McDonald, President of Sinn Féin.RollingNews.ie

Political bettors have rushed to back Sinn Féin leader Mary Lou McDonald to become the next President of Ireland after she hinted at reconsidering her position on Monday.

Having previously ruled herself out of contention in March, McDonald appeared to change her stance when questioned by reporters, stating: “We are not ruling anything in or out.”

Immediately after these comments, betting aggregator Oddschecker reported a significant surge of interest from punters backing McDonald.

On Monday alone, she accounted for 63% of all bets placed on the Next Irish President market—up from the mere 3.4% share she had received during the previous month. 

Before her latest statement, McDonald was rated as a significant outsider at odds of 50/1, placing her behind even UFC star Conor McGregor (33/1) in the betting.

However, bookmakers have now slashed her odds considerably, making her the joint third favourite at 11/1 alongside former Taoiseach Bertie Ahern and former minister Mary Hanafin.

Mairead McGuinness is the current betting favourite at odds of 7/4, followed by Catherine Connolly at 6/1, and Bertie Ahern at 11/1.
