The Latvian president is elected by the parliament, but the public opinion can have an effect on how the parliament votes. Latvijas Fakti asked 500 Latvians, whom do they support for president?
54.3% Aivars Endzins
28.6% Valdis Zatlers
Among Latvian webloggers, it's even much more skewed towards Endzins. Peteris, Aleks and a lot of Latvian language webloggers support Endzins and I have difficulty finding any pro-Zatlers voices.
