Ledic said that his party would vote for Kosor because the HDZ, as the strongest political party in Croatia, championed the Christian Democratic platform, including care for people, family and work.
Kosor's campaign manager Ratko Macek said that the HDZ candidate and "her mobile victorious team" had travelled more than 3,600 kilometres and visited more than 70 towns on the campaign trail.
Kosor is scheduled to hold an election rally in the southern Adriatic city of Split later today and will confront other presidential candidates in a Croatian Television programme in the evening, he added.
Macek cited the results of the latest opinion poll commissioned by the HDZ, according to which Kosor would win 32 per cent of the vote, while her main rival, the incumbent president Stjepan Mesic, would get slightly less than 40 per cent.
"This shows that the elections may be decided in a runoff and that Jadranka Kosor is likely to become the next president of the republic," he said.
