Before 2005, a voter could express preferences for single candidates in either a proportional system ( before 1993) or the mixed majority- proportional system (1993-2005). A candidate had to work the tarmack and meet citizens. As of 2005, a voter has a choice between two names, the rest is handled in the backrooms.

Since the new system has only been used once, the agreements between parties within a coalition are mediated by showings in previous elections. However, were this system to continue over several elections one wonders what sort of criteria would be used to determine the relation of forces within a coalition.
