The Radicals experienced a serious split later in 2008, with several members joining the more moderate Serbian Progressive Party (Srpska napredna stranka, SNS). This led to a crisis in the local government, which was dismissed in early 2009; Vidović was appointed as the leader of a provisional administration pending new elections. An explosive device was detonated under his car shortly after he accepted this position, although no-one was in the vehicle at the time. Vidović described this as an attack on the work he was doing rather than on himself."Trotil za šefa Vrbasa", Novosti, 7 June 2009, accessed 19 March 2021.
