The 2009 election therefore offers the opportunity to examine how political parties outside the USA – where online campaigning has become commonplace – choose to use online tools in their campaigns. This paper examines the online campaign of the German Christian Democratic Union (CDU) with a special focus on the campaign's use of Web 2.0 services. The different elements of the campaign will be discussed with regard to three basic functions of online campaigning provided by the relevant literature: 1) presence in the online information space; 2) support of the infrastructure of politics; 3) creation of symbols for political support and participation. This paper shows that these functions were all present in the CDU's use of online tools in the campaign of 2009engarticle10.1080/09644008.2012.716043http://www.tandfonline.com/doi/full/10.1080/09644008.2012.716043
