Further limitations of electoral representation inhere in its partisan qualities, however necessary they are if elections are to serve as instruments of authorization and accountability (Urbinati 2006). This necessity trades off against others: If speech is always strategic, it will dampen or subvert deliberation oriented toward norm- or fact-based consensus (Chambers 2004, Mansbridge 2004). The deliberative elements of representation are likewise dampened by the that institutions are responsible for decisions affecting the exercise of state power, meaning that they are poor venues for representing emerging agendas, which do much better in restricted give and take of deliberation in the public sphere (Habermas 1996).
