One of the key journalistic jobs in democratic societies is following and reporting during the election campaigns. In that time media, i.e journalists, are teachers of the nation and the tie between candidates in the election and the voters on whose voices they depend on. Media help citizens on informing about election programs, but also about candidates themselves in order to ease their choice on who to vote for. And while the electronic media, i.e their election reporting, are placed under a regulatory framework, that is not the case with the print media, but it is still believed that at least the ethical principles of journalistic profession will be kept in reporting on the elections. There for this paper presents the analysis of reporting of two, in terms of political informing, most important daily newspapers in Croatia, Jutarnji list and Večernji list during the pre-election campaign for the local elections in the City of Zagreb in 2017. This paper attempted to examine the hypothesis that the more liberal Jutarnji list favored candidates of the left political orientation, and that the more conservative Večernji list favored the candidates of the right political orientation, and it is attempted to establish how much did these two newspapers held on to the ethical principles during the reporting. The subjects of the research were cover pages, texts and the ads mentioning candidates for the Mayor position, and the research was concentrated on the representation and the value orientation towards the candidates. In both newspapers all pages, from the cover page to the last page, were analyzed so that the obtained results could be reliable and that the main hypothesis could be explored. The obtained results partially confirmed the hypothesis because Jutarnji list really gave a slight favor to the left-wing candidates. Although both newspapers reported neutrally on the majority of the candidates, they were both found to be violating ethical principles, and in the both newspapers ethically controversial texts and photographs were found.
