Early years (2002–2012)
By August 2003, the headquarters of the Democrats in Kristiansand had reportedly been vandalised eight times. In its first elections, the 2003 local elections, the Democrats ran in 46 municipalities and boroughs, and won 0.3% of the nationwide vote in the county elections. It won two representatives in the municipal council of Kristiansand Municipality, and one in the Vest-Agder county council. In 2005, the Democrats became represented in the municipal council for Bergen Municipality owing to the defection of a Progress Party councillor.
The party stepped up its activity with the aim of gaining a foothold in the Norwegian Parliament at the 2005 parliamentary election. Before the election, party leader Vidar Kleppe tried to bolster support for the party by calling for the closure of all Mosques in Norway if they did not clearly distance themselves from terrorism. Candidates running for the party also had to withstand threats and attacks during the electoral campaign. This included Nordland county leader Amund Garfors receiving death threats, and party leader Vidar Kleppe being physically assaulted both by a former Workers' Communist Party deputy leader, and by members of a demonstration by left-wing organisations SOS Rasisme, the Blitz-movement and Socialist Youth. Despite running a high-profile campaign, the Democrats failed to make any breakthrough in the election.
The Democrats increased their number of candidates for the 2007 local elections, and ran in 85 municipalities and boroughs, as well as in all 19 counties. The party won 0.3% of the overall vote in the county elections, and kept its representation in the Vest-Agder county council. It gained eight municipal councillors, among them in the cities of Trondheim and Kristiansand. For the 2009 parliamentary election the Democrats for the first time ran in all the counties in Norway. The Democrats complained about the Norwegian Broadcasting Corporation to the OSCE, as the party along with other extraparliamentary parties that ran in all 19 counties had been denied television coverage (except the Red Party). Only a few weeks before the 2009 election, the headquarters of the Democrats were broken into, and a computer containing material planned for use in the election campaign was stolen. In the election, the party remained at 0.1% of the vote.
The Democrats had to renew its public registration owing to the poor 2009 election result, and chose to re-register itself as the "Democrats in Norway". The party only ran in 31 municipalities for the 2011 local elections. It nevertheless again won eight municipal councillors, this time in five councils (two councillors in three councils), and held its representation in the Vest-Agder county council. Besides its two representatives in Kristiansand (in Vest-Agder), all of the party's municipal councillors were elected in Hordaland. After the election, the party became part of local cooperations that would govern Kristiansand Municipality and Stord Municipality.
