Passage: Croatian daily newspaper Jutarnji List published an article in September 2012 stating that Grabar-Kitarović was being considered as a possible candidate for the 2014–15 Croatian presidential election by the Croatian Democratic Union (HDZ). It was confirmed in mid-2014 that she was to become the party's official candidate, going up against incumbent Ivo Josipović and newcomers Ivan Vilibor Sinčić and Milan Kujundžić. In the first round of election in December 2014 Grabar-Kitarović won 37.2% of the vote, second to Josipović who received 38.5%, while Sinčić and Kujundžić won 16.4% and 6.3% of the vote respectively.

Josipović and Grabar-Kitarović
