Kramarić was born in Osijek and graduated in philology (Macedonian literature) at the Faculty of Humanities and Social Sciences, University of Zagreb.
But Kramarić, with his boyish looks, calm demeanour and a great sense of humour managed to use media spotlight in order to become one of the most charismatic and popular public figures in Croatia.
Some of more colourful passages, especially those describing the role of local HDZ officials in the opening stages of conflict, brought him great enmity from government and even public threats against his life.
In the spring of 2005, Glavaš embraced regionalism and left HDZ, taking few of Sabor representatives with him and making government majority of Ivo Sanader precariously thin.
In June 2005 Kramarić's attempts to create broad anti-Glavaš coalition failed when Glavaš sided with Croatian Party of Rights.
Glavaš supporters took Osijek-Baranja County while Anto Đapić became mayor of Osijek, thus replacing one of the longest-serving elected officials in recent history of Croatia.
