CD-V & NV-A

CD&V are the Christian-democrats. They have traditionally been the biggest party in Flanders and dominated Belgian politics between the end of WWII and 1999. However, mainly due to the process of secularization they have steadily been losing votes over the past few decades and are now at the same level as the other major parties. They take a vague, centrist stance on most issues and for that reason are often accused of lacking a clear ideological profile. There is a regionalist faction within the CD&V, but in practice they usually end up compromising and accepting the status quo. A running joke in Flanders is that they are regionalist right before the elections and pro-Belgian once in power.
The N-VA is the main successor of the VU (Volksunie), which was a centrist nationalist/regionalist party that imploded in the early 2000's. However, they have more of a right-wing and economically liberal profile. Their ultimate goal is an autonomous Flanders, but they are more moderate and willing to compromise than the other nationalist party, Vlaams Belang. Their message is one of political renewal, transparence, and the elimination of any corruption/nepotism within the administration (particuarly at the federal level, which they are naturally antagonistic towards). On the flipside, they are often 'accused' of being separatists and neo-liberals. Under the leadership of their president Bart De Wever, a gifted speaker, they are now one of the most popular parties in Flanders after five years of political crisis and linguistic squabbling.
