The pre-election campaign of the presidential candidate Bogomil Bonev is the most expensive, according to a research, conducted by Dnevnik Daily. The candidate presidential couple Stoyanov-Kutskova follows Bonev as far as the funding of their campaign is concerned. Petur Stoyanov announced in a TV show that for his campaign BGN 350,000 were spent. According to the Pre-election Staff of the leftist candidate for President Purvanov, his campaign cost much less than that of Stoyanov. However, according to the Daily, the figures announced are much smaller than the real ones. In the campaigns of the candidates versatile means are being used, such as Internet, press, TV and billboards. The billboards read: "Our President" for Petur Stoyanov, "The Strong President" for Bogomil Bonev, "I come because I can" for Purvanov.
